Fantastic stuff!
A few days ago, I discovered that there's apparently a homebrewed SDK, technical documentation, and some demo software available for the 3310: http://nokix.sourceforge.net/help/blacksphere/sub_050main.ht
Maybe next year it would be an interesting challenge to get a game not only running on the proper LCD module, but on the stock phone itself. There's a MAME profile for the 3310, but I have no idea offhand how mature it is or how difficult it would be to turn that into a web build.
