If you just hang it on the wall and do your usual activity in the room, certainly you will see gliders appearing and disappearing at any time. Good tool to make you keep in mind that you are not less than a HACKER :)

I got a green LED bar from a fax machine, I had to modify it a bit — had to short circuit the SMD resistors and make separate wiring for 5x8 LEDs. Then I built a controller circuit around it. It gets power from an ordinary laptop adaptor. This device has become a beloved part of our hackerspace, but since it is built upon a breadboard, sooner or later somebody will disassembly this great equipment. That’s why the documentation is important and I am documenting this for the public - with hope that somewhere and sometime somebody will make this idea alive again.
