The one on the left, with beautiful curved spines, is Gymnocalycium saglionis, and the other one, with white hair around spines is Pyrrhocactus floccosus, a pretty rare one (at least in Japan). Hope they like their new home!
I made a live wallpaper using an Android app called Magic Fluids (https://play.google.com/store/apps/details?id=com.magicfluids) that is fully black, but creates a flame effect every time I tap the screen or slide my finger across it. Yeah, edgy and tacky AF, but it really is a pretty cool effect and I've been using it for years, so whatever.
A step in the right direction, but not nearly good enough. They should be paid for all the time they are required to follow instructions by their employer - basically from the second they leave the locker room in their uniform, right until they dress back into their private clothes after finishing work.
That's how it worked when I was working in automotive industry way back when (the clock in/clock out terminal was right next to the locker room door), and that's how it should work for flight attendants, pilots and everyone else too. Everything else is labor theft IMHO.
