Fancy interacting with a Picard-style LCARS? Thanks to Rob of System47 who made it into a reality. Although I am more of the TNG/ Voyager LCARS but this is still quite nice. The best part would be the Stellar Cartography which, I would just let it run as a screensaver (but not too loud as some sound samples do jump out at you). At first you can try with all the buttons but after reading the instructions, it would make more sense.
