Your blog has quite a few other interesting posts, too. I'll thank you in advance for "wasting" my time. Jay – Thanks, that’s a cool demonstration.

However I could be wrong as I use a box that was made a few million years ago :-) Also if this helps anybody looking at ways of capturing the movement of the mouse in any of their animations, this example on my website may be useful: http://www.databison.com/?p=377 Jay In my experience I’ve found that switching screen updating off and on does speed up things (obviously) but when working with animations and especially on a slow computer, it can cause switchoever to the next “frame” a little sudden and therefore “jarring”.

Cycloids are really neat - the length of one arc is four times the diameter of the circle which traces it. The area under the curve is three times the area of the circle. Cycloids are also found as the solution to a couple of special cases for falling objects. Wikipedia does a good job of these here: http://en.wikipedia.org/wiki/Brachistochrone_curve http://en.wikipedia.org/wiki/Tautochrone_curve In our A-level maths class (so aged 17 / 18 years) we each had to research a particular class of curves and present interesting facts about them (with proofs of course).

I find the macro runs more slowly in 2007, but the chart keeps up with the worksheet calculations. Doug – Interesting.

I find the animation runs about half speed in 2007 (compared with 2000), with the screenupdating turned off and on at each step. That's pretty typical of macros in 2007 that do a lot of interaction with the spreadsheet in my experience. Jon – I do have SP1 installed.
