Just to be pedantic: "speed" = "rate of movement". It does not necessarily equate with "fast". Speed can be any rate of movement, be it slow, fast, stopped or even backwards. I've already had three of my ideas gazumped (people here are much "speedier" than I am..:-), so one more doesn't matter...I'll not get anything done in time for the deadline. (Not that I was getting far with any of my ideas in the 1st place; I kept running into problems outside of my area of skill. Which means I couldn't find a way to make a ball with lots of reflection applied look like a snail or a tortoise or a steam engine or a bullet or......)
