I haven't seen gforce on shrooms neither, but I can imagine that it would be fun
you said hubble... I once downloaded a HDTV-movie (hd is trippy itself, I love it, though I don't have a screen for such manners. and I wouldn't buy one) off a torrent (

) and it was only pictures which hubble made, for one hour, only nebulas and such stuff, dunno if I still have it. (10 minutes later: no I don't have it anymore)
do you know the planet earth documentation? that bbc thingy? I've spent wonderful hours with these

we often just turned off the sound of the video, put in some Boards of canada, smoked several bongs, and woooaaaaaa. that was awesome! I recommend everybody to download these in hdtv from torrents(dot)to
forests, deserts and fresh water are the better ones as far as I can tell.
OMG! now something came to my mind. a few weeks ago I've been to a 3D-IMAX cinema, and I watched a movie about sharks (well, I wanted to see that movie with those normal fish and corals, but my mother already had seen it..).
and I can tell you for sure, you're going to freak out in there on shrooms, seriously. I was constantly thinking how I would act if I was on shrooms in there. Sometimes the sharks look like you could touch them, as if they swam directly in your face.
now THAT was trippy, being underwater with sharks sitting in a normal chair and breathing air
and the 3D effect resulted from different polarised spectacles, not with the red/green stuff, this way, everything looks better, not so green-reddish.
