MORE SPEEDTESTS: http://scratch.mit.edu/studios/795672/ ------- This project shows that if you're switching costume a lot when stamping many things, then you might be better off going through the possible costumes, and searching for all the places where that costume needs stamping, so that you only need to switch through all the costumes once. YMMV with this one, since it does depend on how complicated the costumes are, how many different ones you have, and even on your computer - if you have lots of very simple (vector) costumes, then it may not be worthwhile because switching is quick enough.
