Black to move. How should Black proceed?

A classic example where bishops of opposite colour means the attacker is effectively playing with an extra piece.
… Rxg4
hxg4 Qd1+
Kh2 Qf1 wins
eg f3 h3
Kxh3 Bxf3 etc
Black needs a perpetual, and he needs it immediately since he is faced with Rxh4+, etc. My first thought was 1…Rxg4 2.Rxg4 Qd1+ and 3…Qxg4, but it looks like then 4.f3 stops the hopes for a perpetual. So 1…Rxg4 2.hxg4 h3! must be the solution, opening the diagonal all the way down to h1. Now 3.gxh3?? allows mate by 3…Qd1+ 4.Kh2 Qf3, so White has to set up his own threats, e.g. 3.Qf8 threatening mate on g7, when Black will continue 3…Qd1+ 4.Kh2 Qxg4 and I see no way for White to play for a win, since 5.Qxg7+ looks too risky.
erick, spectacular! I hereby ditch my solution in favor of yours. I missed Bxf3 completely — and probably so did Chucky.
