Steve,

Very cool and thanks for the info and link. Just a month ago I bought into
the Parallax (maker of basic stamp) Propeller. It's a nifty little microcontroller
with 32 I/O pins (4 dedicated during startupt but general purpose after that) 8 cores
all running at 80Mhz and is available for $7.99 in single quantities.  After I spend
sometime with it I'll be taking a look at the picax.

For now though I have a couple of projects that I'm working on that will is being built
around the propeller which is taking up all my "puttering" time.
