I Missed a Chess Brilliancy

I Missed a Chess Brilliancy

I just won a 3+2 blitz game. Nothing special, especially considering my playing level, but computer analysis showed an incredible brilliancy that I missed at one point.

A forced mate in seven, with a queen sacrifice and incredibly rare double-rook epaulette pattern! Does anybody know of other games or chess compositions ending with such a mate?
