I came up with Movin' Diddles during a hack session in Saint-Faustin–Lac-Carré, QC, on a summer road trip I took to the Atlantic provinces of Canada. While I may not be the first to formulate this grid, I have not seen it anywhere else. It starts with double paradiddles and moves the doublestroke backwards through the rudiment, creating a challenge for maintaining strong and precise doublestrokes and relaxed accents as the spaces between doublestrokes, taps, and accents vary.
