I use and like the vector graphics drawing tool Inkscape a lot, but I must say that pattern fills (e.g. crosshatching) are a real weak point of its feature set. They are so flaky and difficult to use!

@pwr2dppl There are some chiral molecules where one stereoisomer is a useful pharmaceutical and the other is toxic (eg penicillamine).

@MarissaKawehi Beautiful shot. Are you a fan of the rotating assigned seating policy at meals? (Or is that even still a thing?)

@jeremyjkun Funny, I’d expect someone to be into one or the other, not both

@bb_sam I also grossly overspecced the battery at an early stage of my design process, which had all these ripple effects making the final design really big, complicating and slowing every subsequent step (big 3d printed case, big lenses, ...). Live and learn.

@bb_sam Really beautiful work! I still hope to get mine up and running some day. I was working with an orientation sensor based on an accelerometer and compass. But in retrospect a gyroscope seems like a clearly superior approach.

@_daviddumas And here is the real life version of the spinorial ball : a device to vizualize 1/2 spin rotation. It materializes the double cover of SO(3) by SU(2) ie unit quaternions github.com/heligone/spino…

@bb_sam I place the luxball app in the public domain, so you can use it and things derived from it as you like. You can include attribution if you think it appropriate but you do not need to do so. Thanks for asking!

@littmath This comment made my realize why I could never program a VCR correctly. I simply didn’t understand Gal(Qbar/Q) well enough.
