I've been playing with PD almost daily since the move, and boy is it fun... it's even better with LoopBe1 an internal midi loop which let's you send and receive midi data in the machine.
I've found alot of stuff on chip-tunes and Lo-Fi sounds for PD on the web. Most notibly mmonoplayer.com has emulated the sound chips from several classic consoles. http://mmonoplayer.com/mspexternals.php They're mainly patches for MAX/MSP but some of the good stuff is available for PD as well.
loads of fun
