Well this one just finished, it's not that great for how long it took, I studied the glass beads more to see that there was a volumous look to the caustics, so I tried to reproduce that here. I also looked at some physics pictures online to try to get it perfect. So be kind, this took 4 hours to render. and uses 145 lights. 4 spotlights 1 cylinder and a farking wack of metaballs.-
