C4D4U’s SOFTBODY TETRIS V16 is (as the name implies), the latest in a series of “softbody” simulations of Tetris, in which the tetronimoes are rubbery, jelly-like solids that glisten as they wobble into place. It’s an incredibly soothing thing to watch (C4D4U calls them “ASMR for my eyes”) and part of a wider genre of softbody sims. JWZ argues that this “becomes intolerable” upon the “realization that completed rows don’t liquify” but if that’s your thing, you need SOFTBODY TETRIS V9.
