A fan has gotten very creative and taken images from TOS and stitched them together to get a glimpse of what the original series would have been like in widescreen. I love this idea and these pics are amazingly cool! Check them all out at the link below...

Those pictures like great! I would love to see TOS in widescreen.
I looked at these on the Facebook group. Some of those with multiple clones of the main cast in shot are almost surreal but you get a good view of what the show could have looked like if life had been different.
They are amazing.
