I've uploaded version 1.1 of GammaFV to:

http://www.carrotworks.com/

GammaFV is a simple Mac OS X IGC file viewer that plots the geographic
trace of a flight onto a terrain, satellite or road map.

Version 1.1 can now colour the trace with vertical speed data.

Vertical speed colouring might be a bit slow on older PowerPC based
machines. I'm using the HTML based mapping engine in a way that it wasn't
really designed to be used.

Don't expect too much from this software. It doesn't do tasks, airspace,
scoring or anything like that.
