The Stock Market Planetarium looks extremely cool. I'll have to go to the Art and Money Online exhibition at Tate Britain (March 6 till June 3 2001).

Talking of which, Signatures of the Invisible is an exhibition of art and physics (March 1 till March 29 2001 in East London) which appears to tap into one of my favourite images: That of the track left by particles being created and destroying in an accelerator. Should be good; I'll be going soon.
