I'm aware of tidal being used for
- music (a lot of approaches and genres that could be listed here..)
- patterning video, e.g. dance dirt for choreography, Didactic pattern visualizer, ofxTidalCycles and tidalp5 for visualisation of music performance
- weaving, e.g. on the tc/2 loom
- lights (via DMX)
- robots (via strudel and webserial)
What else could be / has been patterned (and/or live coded) with tidal? Maybe ..
- other textile patterns (braiding / knitting / shaft looms / tablet weaving etc etc)
- Bell ringing/change ringing
- Juggling siteswaps
- laser/craft cutters
- 3d printers
- CNC routers/mills
- food/cocktail recipes
- Electrical muscle stimulation
- clocks
- orreries
- plant growth
- what else ???
