The space is 5200 square feet and they’ve managed to cram a lot of different uses into it. There’s areas for computers and electronics, crafting and sewing, a dark room , [...]

White board beats chalk board, LED marquee beats white board, and an LED white board trumps them all. This hybrid lets you draw on the surface with dry erase markers while Conway’s game of life plays out underneath. [Bert] sent us this tip after seeing yesterday’s office marquee. This version is quite similar in appearance but [...]
