I was always reluctant to experiment with epoxy & resin because I thought it would be messy. Man is it a sticky mess. What I didn't appreciate was how different it is than painting. There is such a short window to work with the paint before it hardens leaving little room contemplation, only action.
Below is a 5-layered piece with iridescent paints; there are a few more examples on my homepage. I'll share more details about my idea with this project soon.. one of these years.
