Bubbles-in-a-plane was inspired by ideas from Anthony Villaveiran and Carl Hoff, posted at the Twisty Puzzles Forum. Unlike a convention Engel's Enigma, the rotating parts do not have sixfold symmetry and they are unequally spaced. The result is a quite confusing puzzle that jumbles (bubbles?) and is fudged. The name of the puzzle hints to Antony's nickname "Boublez".
