303 acid ring tones

For those not in the know, the 303 refers to the Roland TB-303, a primitive synthesizer/sequencer, originally designed as a poor-person's replacement for a bass player, but which has since then become massively popular in techno/house/trance music because of the resonant squelching noises it can make when you tweak the knobs. Actual 303s sell for thousand dollars a piece; despite their cheap construction, there were only 10,000 or so made before Roland realised that it was a crap substitute for a bass player and canned it.

The 303 itself is a simple device; there is software (such as ReBirth) which emulates it accurately, and making a 303-like sound generator on a chip should be relatively easy. Given that a 303 contains a 16-step sequencer, it would be natural for repeating sounds, such as ring tones.

Which brings me to my idea: design a 303 on a chip, make it cheap, embed it in mobile phones (ideally those with a fluorescent/transparent/glittery appearance), and you have something more novel and cooler (at least for E-popping raver kids) than the usual beepy renditions of classical motifs/folk melodies. Allow the ring-tone editor to control resonant filters, envelopes and such as well as the notes, or put in a randomiser to allow each user to generate their own variant.
