What did you make today?

[glatt]

Yep. Did I mention that last weekend my car rolled off of the jack as I was lowering it? I had just put the wheel back on with the lug nuts finger tight, and as I was lowering it, it just slowly rolled forward and off the jack. Scared the crap out of me. The brick I was using as a wheel chock did nothing because I apparently had it on the uphill side of the wheel and not the downhill side of the wheel. I had had the car in neutral with the parking brake off because I wanted to spin the wheel to check this one caliper that was slightly rubbing the rotor. (I cleaned it and greased the caliper sliding pin and it's better now.)

Anyway, nothing got hurt and it just came down faster than I meant it to, but it made me wish I had some proper wheel chocks.

Operator error was entirely to blame, but having these massive chocks will be a visual reminder to secure the damn car so it can't roll. They are 6 inches tall and match the curvature of the wheels pretty closely.
