More proof that it takes (x) years to make an overnight success: Karlsruhe-based communications designer Felix Vorreiter invented the txtBOMBER back in 2005, but it's just in the past few days that it's exploded onto the blogosphere.

What is it? It's basically a handheld skywriter that prints on walls using an Arduino processor and seven markers. Pretty damn rad!
