There were a few tricks on there that I didn't know (or maybe had forgotten ), and the pentagon was particularly awesome. I also liked the magic pencil.
[Edit: Just realised the pencil isn't magic, it's just that the ruler-pencil and compass-pencil are different colours. Still makes things a lot clearer though.]
I think it'd be a lot better if you had a bar along the bottom, so people could go back and forward at their own pace (like in YouTube, for example). A pause button would be good too, so people could follow along.
Why did the vector cross the road?
It wanted to be normal.
Thanks Mathsy ... it took a lot of time and patience to put them together. Forward and rewind would be hard, put pause is possible I think.
I just hope I made no mistakes, as I will link to them from the main website soon.

Really nice job. Excellent!
In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
No great discovery was ever made without a bold guess.
