What was Black thinking?

I observed a pretty wacky game of chess at my local club this evening. Black thought it was a good idea to sacrifice his queen, expecting to be rewarded with at least some compensation. However looking at the game from an elevated (and sideways) observation point I couldn't see exactly what he was expecting. I turns out that there was compensation, in that both players were under 5 minutes after about move 10 (60m+30s was the time limit), and in the ensuing complications, White ran out of time!
Here is the start of the game, as I got sidetracked playing my own game, and was not able to see the rest. White's flag fell around move 30
