Did I already show these colored oil-disks (“lava lamp projector disks” I think?) that I got for ligra? :>

it’s a glass disk with two chambers with several, non-mixing, colored fluids inside, that will create super lovely bubble-textures! I think this was invented by the same company that invented the lava-lamp. They also sell such disks.

Now I need to design a fit that can also rotate the disk in this half-ligra. It’s too large for all four metal beams :D
