I'm trying to learn M2 and 4BLD this summer (I currently use Old Pochmann with color-pair memo). I made a little tool to help practice letter-piece mappings, letter-pair to image mappings, etc. It's pretty basic right now - press spacebar, click, or tap to get a new random card from the set. You can also set a BPM to use it as a metronome. It's harder to explain than it is to use, check it out and tell me if it's useful or what I should add.
