Courtesy of Casual Gameplay, I discovered the graceful, monochrome simplicity that is Gimme Friction Baby (it’s the center one of the five games at the top of the page, with the big white cannon).
I didn’t read the rules (are there any?), but the gameplay should become apparent after a few mouse clicks. That’s all you do–click your mouse button at the right time. And yet it sucked up a half-hour of my Friday morning.
My top score? Four.

I agree… very addicting. Made to 8 points though!
Good one. Made it to 10 points a few minutes ago on my third play today.
Eeeevil! I need to stop following your links to time-wasting games, but your recommendations are always pretty solid, and I have no willpower.
My best was 5.
