GTA-VC, BTT Hill Valley-mod 0.2e: 1-minute timetravel to the future.
The coolest mod I ever encountered during my timetravels :-) All credits go to the people at http://www.bttfhillvalley.co.uk/
The best thing is, they succeed! Well, in time, I'm sure! It's a work in progress. They have made a GREAT job on this one so far!
