Geek, just checked out your tutorial. Neat technique. I think you meant to say "Cube" instead of "Cylinder", but the pictures make the approach very clear. Nice job. Also, a similar trick could also be used for - you guessed it - a blinking eye! Or a squinting one. Add a slightly smaller sphere, and maybe something more like a hemisphere, instead of the three quarter sphere for the upper eyelid. I'm off to give it a try, except I'll have to build my sphere parts in the vertex modeler; the boolean function tends to crash my computer. --Terri
