[Edit again!] iScience clips are now online at BBC – Learning Zone.
[Edit] Now that March 12th has past, iscience is now longer on BBC iplayer.
My work on BBC iScience is on iplayer again now. This particular episode is nanotechnology. (Can I get a woooOOOooo?) Pretty much all of the 3d graphics are my creation, even the ones which seem at first glance to be 2d. They are cel shaded 3d! (Same approach as on Futurama) They include animations on fusion, uv radiation, cell division and all sorts.
