Correction to the above:
Don't use -geometry to change the scale, use -sample as orginal poster said!

find ./ -name '*.gif' -exec convert -sample 50% {} {}.png \;

Otherwise it complains that it can't find the files! Took me a little while to 
work out why it was overwriting my files with a 0 byte file :) That teach me to  
RTFM - thank god for backups.

Whether you think you can,
Or whether you think you can't,
You're right.
