There's an interesting interview here, on SymbianOne, with The Astonishing Tribe (TAT), who are behind the transitions and other animated elements in S60 3rd Edition FP2 and also, apparently, behind the Samsung i450's novel Music player application. While you're visiting you might also want to read this piece on a UIQ developer's perspective on the Symbian Foundation. Both are well worth a read over lunch or tea!
