official webpage of the Nobel foundation is wonderfully comprehensive, with everything from educational games to science documentaries to live webcasts of the awards.
Most commissions for the banquet, from Swedish suppliers, are available commercially as well. A bit on the pricey side for every day use, but great souvenirs for the design oriented. Beats a plastic viking helmet.
