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

Not sure how clear this is from the first post. All liquids have different viscosities and won’t mix, meaning, that they all will flow, trying to be separated by gravity, creating these lovely blob shapes. It’s a gentle process and very trippy and random. Now, by slowly rotating the disk, this process can be stimulated
I think this also highlights why I wanted to work on my own projection system instead of buying some Gobo or Dia projector. I want to be more creative than just putting some stencil or Dia inbetween :3
(Uh, and don’t get me wrong, I don’t want to claim this effect or anything. To whoever thought of this, the colored oil disks: what you’ve created there is amazing and works so well!!)
Uh, I also got two more color combinations, an all red and all blue tones one. I’m hyped for the blue one, it’s so ocean-y ~ 🥺

It seems these disks are built as follows:

- Outer glass with a perimeter of silicone
- Chamber with two different colored liquids and air
- Inner glass, again with a perimeter of silicone
- Another chamber with two differently colored liquids and air
- Finally another glass slide

This sandwich of glass, liquids and air, sealed by silicone is protected by a plastic shell, which also provides an option to mount and rotate it with an external motor

I feel like you could easily prototype a DIY version with microscope slides. They are cheap and widely available, for effect you can simply turn them like an hourglass!
@janamarie petri dishes might also work quite well and would be relatively easy to seal? Or are they too deep?
@HeNeArXn oooh, interesting!! might be too deep though
