I've finished a piece recently that was inspired by the blinking universe theory. If you haven't heard about it this guy Richard Lighthouse proposes the universe is not constantly existing but blinks on and off between the physical and nonphysical.
I decided to do this interpretation in a way that expresses reality as being both physical and considers thought to be a physical expression as well. The abstract representing the universe as being off, and the other half as the universe being back on again.
The ideas came from this guy: www.rlighthouse.com
It can also be found on a kickass podcast I listen to as well, pretty interesting stuff.
