I work for BUG Labs. In my spare time I've been playing around with some ideas for using libpd on our device. I put up a blog post about my work here: http://community.buglabs.net/aturley/posts/240-libpd-Embedding-Graphical-Pro...
Nothing revolutionary, but I thought people might enjoy seeing Pure Data on yet another platform (in this case, running in OSGi on ARM).
