I whipped up this new jsui controller during my layover in Phoenix:

So far it's only about 500 lines of messy code, but works well for the basics. Assigning the side values to various softsynth parameters is great fun, and will be even better once I get a central drag point coded. It also functions as a horizontal/vertical slider, range control or combo volume/duration control. A few more bells and whistles and I'll roll it into the Daevlbox tools release.

It's named after the central character of Edwin Abbott's Flatland, which I read (yet again) while in the rust red wilds.
