I quite like the idea for flowful. I was quick to buy Brian Eno’s apps Bloom, Trope, and Air a few years ago, although I haven’t splurged for his more expensive Reflection.
I’ve also used some white noise generators for work and relaxation, none quite to my liking, but hopefully they will get better.
I was also reminded recently about an early piece of shareware software called Musinum by Lars Kindermann that generated music from fractals. I pulled up the software page again and see it no longer runs under Windows 7 and beyond. But for those with some curiosity in the subject, this might be of interest.
ps: the link on the BoingBoing thread doesn’t point here, I’m not sure why that happens. Oh never mind, I think it just sorted itself out?
