Draw in the air with a 3D printing pen

We live in the future. The lack of jetpacks gets a pass.

There is a moment in the Kickstarter video for the 3Doodle pen (which I found via the New Scientist's Paul Marks) which took my breath away. It comes after the introduction, when the pen is used to draw its own logo; and it is as simple as drawing a cube.

Only… it draws all of the cube:

The pen is essentially a handheld 3D printer. By extruding heated plastic through the nib, which then cools solid almost instantly, it lets users "write" in thin air, creating anything from relatively simple stick figures:

 

To insanely complex wire art:

 

(The 3Doodle team have joined forces with a bunch of Etsy wire-artists to show off the pen. The work above is by Ruth Jensen.)

On one level, the pen is clearly "just" a $75 toy. A few artists might find use for it (but then, artists find uses for anything), and it looks like it would be amazing fun to just goof around with, but it is difficult to imagine it revolutionising anything. And I'm pretty sure the launch-to-penis time (the time it takes for a radical new creative technology to be used to make crudely-drawn cocks) will be in the microseconds.

At the same time, though, it's a demonstration of just how close-to-market mainstream 3D printing is. The over-arching technology behind the 3Doodle genuinely does have the potential to shake up manufacturing — if not by letting people print consumer goods at home, the utopian dream, then at least by radically restructuring supply chains in conventional production.

The pen is currently less than $1000 short of its $30,000 goal on Kickstarter. I really want one.

David Lammy calls for parliament to overturn the EU referendum result

The Labour MP for Tottenham said Britain could "stop this madness through a vote in Parliament".

David Lammy, the Labour MP for Tottenham, has called on parliament to stop Brexit.

In a statement published on Twitter, he wrote: "Wake up. We do not have to do this. We can stop this madness and bring this nightmare to an end through a vote in Parliament. Our sovereign Parliament needs to now vote on whether we should exit the EU. 

"The referendum was an advisory, non-binding referendum. The Leave campaign's platform has already unravelled and some people wish they hadn't voted to Leave. Parliament now needs to decide whether we should go forward with Brexit, and there should be a vote in Parliament next week. Let us not destroy our economy on the basis of lies and the hubris of Boris Johnson."

Lammy's words follow a petition to re-run the referendum, which has gathered 1.75 million signatures since Friday.

However, the margin of victory in the referendum - more than a million votes - makes it unlikely party leaders would countenance any attempt to derail the Brexit process. On Saturday morning, Labour leader Jeremy Corbyn said there should be no second referendum. Tory leader David Cameron has also accepted the result, and triggered a leadership election.

It is true, though, that had Britain's EU membership been decided in parliament, rather than by a referendum, there would have been an overwhelming vote to Remain. Just 138 Tory MPs declared for Leave, compared with 185 for Remain. In Labour, just 10 declared for Leave, versus 218 for Remain, while no Lib Dem, Scottish Nationalist, Plaid Cymru, Sinn Fein or SDLP MPs backed Leave.

Rob Ford, an academic who has studied Ukip voters, said Lammy's call was "utter madness":
