Jtnimoy has a downloadable version of GRL's L.A.S.E.R tag new brush style for their light / art projection system (source is on the site too) -

I coded this brush that turns a few mouse drags into a randomly generated bubbly blingy style. The brush code was then massaged into L.A.S.E.R. Tag. Here is the stand-alone version for your enjoyment and algorithmic plagiarism. I should quickly note for interested jttoolkit participants that this begins my attempted merging/joining/cooperating between OpenFrameworks and jttoolkit in hopes that they could eventually be one in the same ACU strain.
