Thank you, evolution, for making me good at Super Hexagon

A paean to pattern recognition and twitch gaming.

Our inherent ability for pattern recognition gets a bad rap these days. It makes us see faces where there are none, think we've cracked the secret to winning the lottery, and lose at games of poker. When it helps us, it's usually perceived as obvious. "Well of course that 'danger: meltdown imminent' warning light stands out; it's the only one that's turned on!"

The subtler moments when pattern recognition helps are rare these days. We don't frequently worry anymore that a patch of long grass rustling in a different way to the rest of the savannah might be hiding a lion. And, well, I don't drive. So that benefit goes out the window.

But, joy! Finally a use for my innate ability to unconsciously recognise repetition and adjust my expectations accordingly: it makes Super Hexagon really fun.

Super Hexagon is a minimalist game for iOS, Android and PC/Mac which involves moving a small triangle around a hexagon, avoiding the beams of light coming towards it. It is, as with so many of the best mobile games, as simple as it is addictive. It is also nearly impossible.

High scores are measured in seconds. My highest on the most difficult level I've unlocked — the fifth of six — is just over seven seconds. Watch a video of the game, which cycles from the easiest to hardest level and, if you've never played it before, everything will appear to move faster than anyone could possibly respond to:

But here's the thing: the game is based on patterns. Each playthrough is different — there's no rote memorisation of waves of motion, like there are in many "twitch" games — but gradually you will learn that certain effects are linked. You will learn this subconsciously, because the game is far too fast-paced for your conscious brain to have much to do with anything, and the result will be time slowing down. What seemed impossibly fast when you first saw it appears to move at a sluggish pace, and you'll find yourself screaming at the tiny triangle — which once moved with so twitchy a response that you would overshoot targets — to get a move on.

It's my own very mild superpower. I might not save me from being eaten alive, but it nudges my high score up by a couple of seconds.

The City of London was never the same after the "Big Bang"

Michael Howard reviews Iain Martin's new book on the legacy of the financial revolution 30 years on.

We are inundated with books that are, in effect, inquests on episodes of past failure, grievous mistakes in policy decisions and shortcomings of leadership. So it is refreshing to read this lively account of a series of actions that add up to one of the undoubted, if not undisputed, successes of modern ­government action.

Iain Martin has marked the 30th anniversary of the City’s Big Bang, which took place on 27 October 1986, by writing what he bills as the inside story of a financial revolution that changed the world. Yet his book ranges far and wide. He places Big Bang in its proper context in the history of the City of London, explaining, for example, and in some detail, the development of the financial panics of 1857 and 1873, as well as more recent crises with which we are more familiar.

Big Bang is the term commonly applied to the changes in the London Stock Exchange that followed an agreement reached between Cecil Parkinson, the then secretary of state for trade and industry, and Nicholas Goodison, the chairman of the exchange, shortly after the 1983 election. The agreement provided for the dismantling of many of the restrictive practices that had suited the cosy club of those who had made a comfortable living on the exchange for decades. It was undoubtedly one of the most important of the changes made in the early 1980s that equipped the City of London to become the world’s pre-eminent centre of international capital that it is today.

But it was not the only one. There was the decision early in the life of the Thatcher government to dismantle foreign-exchange restrictions, as well as the redevelopment of Docklands, which provided room for the physical expansion of the City (which was so necessary for the influx of foreign banks that followed the other changes).

For the first change, Geoffrey Howe and Nigel Lawson, at the Treasury at the time, deserve full credit, particularly as Margaret Thatcher was rather hesitant about the radical nature of the change. The second was a result of Michael Heseltine setting up the London Docklands Development Corporation, which assumed planning powers that were previously in the hands of the local authorities in the area. Canary Wharf surely would not exist today had that decision not been made – and even though the book gives a great deal of well-deserved credit to the officials and developers who took up the baton, Heseltine’s role is barely mentioned. Rarely is a politician able to see the physical signs of his legacy so clearly. Heseltine would be fully entitled to appropriate Christopher Wren’s epitaph: “Si monumentum requiris, circumspice.”

These changes are often criticised for having opened the gates to unbridled capitalism and greed and Martin, while acknow­ledging the lasting achievements of the new regime, also explores its downside. Arguably, he sometimes goes too far. Are the disparities in pay that we now have a consequence of Big Bang? Can it be blamed for the increase in the pay of footballers? This is doubtful. Surely these effects owe more to market forces, in the case of footballers, and shortcomings in corporate governance, in the case of executive pay. (It will be interesting to see whether the attempts by the current government to address the latter achieve the desired results.)

Martin deals with the allegation that the changes brought in a new world in which moneymaking could be given full rein without the need to abide by any significant regulation. This is far from the truth. My limited part in bringing about these changes was the responsibility I was handed, in my first job in government, for steering through parliament what became the Financial Services Act 1986. This was intended to provide statutory underpinning for a system of self-regulation by the various sectors of the financial industry. It didn’t work out exactly as I had intended but, paradoxically, one of the main criticisms of the regulatory system made in the book is that we now have a system that is too legalistic. Rather dubious comparisons are made with a largely mythical golden age, when higher standards of conduct were the order of the day without any need for legal constraints. The history of insider dealing (and the all-too-recently recognised need to legislate to make this unlawful) gives the lie to this rose-tinted picture of life in the pre-Big Bang City.

As Martin rightly stresses, compliance with the law is not enough. People also need to take into account the moral implications of their conduct. However, there are limits to the extent to which governments can legislate on this basis. The law can provide the basic parameters within which legal behaviour is to be constrained. Anything above and beyond that must be a matter for individual conscience, constrained by generally accepted standards of morality.

The book concludes with an attempt at an even-handed assessment of the likely future for the City in the post-Brexit world. There are risks and uncertainties. Mercifully, Martin largely avoids a detailed discussion of the Markets in Financial Instruments Directive and its effect on “passporting”, which allows UK financial services easy access to the European Economic Area. But surely the City will hold on to its pre-eminence as long as it retains its advantages as a place to conduct business? The European banks and other institutions that do business in London at present don’t do so out of love or affection. They do so because they are able to operate there with maximum efficiency.

The often rehearsed advantages of London – the time zone, the English language, the incomparable professional infrastructure – will not go away. It is not as if there is an abundance of capital available in the banks of the EU: Europe’s business and financial institutions cannot afford to dispense with the services that London has to offer. As Martin puts it in the last sentences of the book, “All one can say is: the City will survive, and prosper. It usually does.”

Crash Bang Wallop is not flawless. (One of its amusing errors is to refer, in the context of a discussion of the difficulties faced by the firm Slater Walker, to one of its founders as Jim Walker, a name that neither Jim Slater nor Peter Walker, the actual founders, would be likely to recognise.) Yet it is a thoroughly readable account of one of the most important and far-reaching decisions of modern government, and a timely reminder of how the City of London got to where it is now.
