SDL, alas indeed! I have the feeling this is one of those which gives out first - computer memory or patience (?) deals. I once tryed 3dtranslate "exploding" 3000(don't actuall remember how many but there were a lot of 'em), little cubes for stars; it took a while even though I thought I broke bryce 2 or three times as I kept movin' the little buggers, but it worked. - TJ
