I should probably clarify that that's QML extended by some custom C++ I've written. QML doesn't out of the box have anything appropriate for some of this stuff, but I've written that code for videos before so I can reuse that.
I hear that the presentation template for the next event I'm teaching at is bad and instructors who ask are being told that they should just go with a neutral dark background instead of trying to use it. I might rework the whole thing in QML anyway (I use that for the visuals in a lot of my videos) so that would simplify matters a bit.
Just saw someone recommending the local videos on my PeerTube server on a forum instead of linking people to the YouTube channel. https://video.typica.us/
The coffee on the left is lighter than the coffee on the right. The coffee on the bottom is the ground version of the coffee on the top (with greater difference for lighter coffees than for darker coffees)
This development sort of makes me wish I picked up some of the puzzles I saw last time I was in S. Korea.
Good dog.
