Has anybody here played around with this awesome (and free!) space program? I've had it on my computer for years (BeOS version, now Mac) - but I never really saw how amazing it is until I got a computer fast enough to have fun with all the features. With high-resolution replacement textures, it's mind-blowing. There are some fun add-ons too. Check out these screenshots I just took:
Jupiter and Europa

Saturn

Here are some add-on models from 2001: Space Odyssey. (needs Blue Danube music)

Discovery

"Open the pod bay doors, HAL."

"My God, it's full of stars." (sadly, it's not)
