RedPDU

livecoding via sms anyone? an expensive and annoyingly hard hobby for sure.
but the RedPDU supercollider class makes this possible in any case. it can decode mobile phone text messages in the pdu format. and with a serial connection to your phone (bluetooth or cable), it is easy to directly download incoming sms from your phone into supercollider and interpret them. no additional hardware required.
the class is available here. (there is also a mxj java version for max/msp called f0.pdu here)

and here's a short demo video where i send a short message to myself...

RedPDU from redFrik on Vimeo.

the code i texted in this video was...

Pbind('degree', Pn(Pseries(0, 2, 5), 4), 'dur', 0.1, 'amp', 0.5).play

and the sc receiver function is in the helpfile. but note: on many phones it is impossible to type characters like {} [] \ | etc. you might want to add some find&replace functionality and use <> meaning curly brackets etc.
