A new robotics project on Kickstarter is promising to draw any web-sourced graphic onto your wall using erasable markers. When you get tired of the piece its drawn on your wall, it has the ability to go back and completely erase it.
The device hangs from two pins on the wall in a pulley-like mechanic, and uses four markers to create the images, which can be up to 2.5m x 2.5m. The technology is called a ‘vertical plotter’.
Presumably Scribit works best for line drawings and the like, but apparently it has the ability to fill in areas of solid colour in the same way we do — by going back and forth until it’s full.
