Darren cook has released an open source project on source forge for charting. It looks pretty interesting. You can see it here:

Bytearray.org which has some incredibly cool experiments posted another bitchin project for doing page flipping. An engine which does some incredible parsing to create a realistic effect.
Check it out here: Check out the page flip effect here
Also another set of experiments on bump mapping:
This came from Mr.doob from the papervision mailing list which really shows some wild effects with a papervision cube.
I had a chance to play with papervision and I must say it is absolutely phenomenal and has major potential for a new generation of 3d demos. John Garden has been instrumental in showing the power.
You can render in about 8000 polygons on a decent processor which makes it ultra cool. I also found some other neat links.
