Black is very weak on the black squares so...
1. Nxg7 Kxg7
2. Qh6+ Kg8
3. Rxf4! exf4
4. Bf6 Bxf6
5. e5! Nxd3
6. exf6
and White eventually mates on g7.

The right ideas, but please elaborate a bit more... even the "eventually mates" part is interesting... (and note that the move order isn't the precisest one)
6. ... Nf7+
7. Kg1 Nh3+!
8. Kf1
If White takes the knight his king will become critically exposed to checks from Black's queen and bishop (and rooks, if it wanders to e1!)
8. ... Bc4+
9. Ne2!
This is important - White needs to make himself a shield to hide behind, if he runs to e1 straight away he'll get mated.
9. ... Bxe2+
10. Ke1!
And that's that.
Edit: In the line I originally gave, Black can play 3. ... Bxg5, so White should leave Black's king on g7 and play the rook sac first:
1. Nxg7 Kxg7
2. Rxf4!
Now 2. ... Bxg5 fails to 3. Qxg5+
2. ... exf4
3. Qh6+ Kg8
etc.
if 3. ... Kh8
then 4. Qxf8 is mate. It took me several minutes to see that!

Another tactical position, for our enjoyment, anyone?

OK:
