The main idea of Stackenlichten is to perform retro pixel animations on RGD LEDs, that can be nicely arranges. In order to hve a specific architecture, the LED cases are in shapes of triangles, that can be attached to each other using their two magnets on each side.
At the 32c3 I saw a town sign “Bad Gateway” with the addition that it’s a “Internetkurort” (internet health resort), so I decided to do a vector graphics of that and print stickers. The graphic (see license in the footer) is realized with LaTeX and TikZ and even uses the original german font for street signs as well as the original color for town signs. The stickers are quite transparent, but if you are interested, just give me a note, I still have some left.
