Luc Verhaegen is a bedroom hacker whose focus is almost solely on modesetting, he started http://unichrome.sf.net/ and spends most of his time bashing VIA.

Some examples of the resulting cruft are shown and some shortcomings examined. Current developments are explained and possible future directions are explored.
