This started out as a demo for the depth-of-field sprite object, but quickly metamorphosed into something involving blendmodes, bitmap sessions, marbles…
With the tiled atoms in the background, strictly speaking the dof shouldn’t be apparent at all, but i do suffer from tweak obsession, so probably best to leave it. I may do another demo soon to illustrate the DofSprite2D object in more detail. For now, enjoy! Although please don’t stare at the background too long – might do irreversible psychological damage.
