Triangle-grid LED display

[Dearmash] put together this RGB LED display using triangles for each pixel. It’s an interesting deviation from the traditional grid layout. There are two video demos after the break. The first is a plasma-style pattern generated in Processing. The second is a spinning color wheel which would be perfect if synchronized with your Photoshop color spinner.

So the physical build is done, and now [Dearmash] is looking for a purpose for the device (isn’t that always the way it happens?). He mentions that the triangular layout looks cool, but makes text display almost impossible. Does anyone have any ideas on how to make this work? Right off the bat we could see side-scrolling a font similar to the Metallica logo’s M and A. Bu there must be some way to group these pixels together into readable characters. If you always use an upward and downward pointed triangle on the same row as a pixel it makes a parallelogram which would be used to display italicization characters.

Thingiverse Receives First DMCA Takedown

A landmark in home 3d printing was set when [Dr. Ulrich Schwanitz] sent a DMCA takedown notice to Thingiverse.com on users [artur83] and [chylld's] takes on his Penrose triangle model. ([chylld's] take is pictured above) While the takedown itself is highly debatable, we do think it’s cool that home 3d printing has come far enough to begin infringing on the copyrights of objects themselves. Right now media pirating has the front stage, but it’s not hard to look a little further into the crazy sci-fi universe that is our future and see a battle being fought over the rights to physical objects.
