I had a similar idea, with morphing my autodeco to change brick colors rather than deco them, so you could make a set of colors to change to, speed inbetween each change, and then run it. Im lazy, of course, but anyone whos not should try that.
Zor just pointed me to this topic and you guys should know, my scripting projects have led me in this direction over the last few days. If there's such a demand for it I can whip up a non-scripter-friendly version in short order.
