Adobe’s Flex 2 seems like the realization of some great RAD concepts. I’ve seen this for MS related products: Access, VB, etc. However, it’s my first time seeing it for a clean rich Internet application UI. The fact that you can use it along w/ Eclipse is pretty attractive. If ya have 12 minutes, check out this demo.
Some guy built a Commodore C64 Emulator. Here’s a screenshot below — you can actually play the games. If your interested, check some of the other projects Flex Derby developers built — for some contest Adobe held. Pretty slick!
