From eca61962be628c59ad39dd23e2e286fdd21e7680 Mon Sep 17 00:00:00 2001 From: Alan Alpert Date: Fri, 16 Sep 2011 13:26:50 +1000 Subject: Fill out examples a little more Adds an example of colorized ImageParticle, and an example comparing the particle system to dynamically created Images (which don't do too badly when they're kept really simple).
