Lady Ada has a great reputation for creating DIY projects that are fun and easy to build. A couple of years ago, I built her MiniPOV kit which is a Persistence of Vision toy and I quite enjoyed the project. It was very easy to build with wonderful directions and was a kick to play with too.
Now Ada (working with Robert Quattlebaum) have come up with the YBox 2 kit based on the YBox from the Yahoo Hack day. The YBox2 is a network connected set-top-box based on the Parallax Propeller microprocessor. The YBox 2 supports NTSC or PAL, Ethernet (with DHCP), IR remote, and a network bootloader...and it all fits in an Altoids tin! This looks like it could be a great platform for those looking to learn about the Propeller and you end up with something that's usable...not just a pile of generic parts and a protoboard.
