The enhanced Al is so good I use this supplier's metal for laser pump chambers.
there's a user here from africa (sorry i don't remember his name) that was doing lumia cymatics by projecting lasers through water that he was rippling with oscillators. really beautiful stuff.
suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
