“Acrylic Pouring Kalaidoscopes”

2D and 3D examples are included here.

Projected large, these kalaidoscopes are mesmerising, especially in 3D.

Note: If you stare into the centre of the 2D kalaidoscopes (or the 3D ones if you are actually viewing them in 3D) then when you look away, you will find the universe bending! Try it and see.
