sorry, JF, lol...well, better late than never
i thought that was obvious but i think nobody got it or maybe they did and just did the usual
lol...i was just inspired at some point last weekend as people were talking about what they saw when they looked at pic and it reminded me of some of my fave optical illusion pics (i used to love going to the Ontario Science Centre and eating up all that sort of stuff)
anyhow, i thought the 'old woman' one was famous (so i landed her on Gord's sunburst head for a gag
) but maybe not...when i was little all i could see was the old woman but i notice as i get older that now all i can see is the young woman, lol
note: the reason i took so long to reply was that i got sidetracked...i went to search and typed in 'optical illusions' innocently but landed a bunch of naked people pics which had me turning my head sideways and even upsidedown and then backwards...sometimes i think my ISP $charge is a rip off, other times it's a real bargoon! lol
