[OSC_dev] Images ?

[Gaspard Bucher]

Your products look really nice ! I understand your need for a simple
picture tag. "p" seems just fine.

By the way, we are working on a small set of common osc
idioms/features to help applications and controllers talk to each
other: http://rubyk.org/oscit

It would be really great if you could join in ! I'd love to see
something like the MagicQ being controlled or controlling rubyk or
other oscit enabled applications / hardware.
