We recently sang the praises of Sega’s Homestar Planetarium Pro, and we have just found out that this September we will be treated to its latest software, the Blue Earth Disc. The original gadget, designed by Takayuki Ohira, came with two colored star discs and one of the moon, while this one is a detailed CG of what our very own planet looks like from space. Expect its debut this September. If all goes according to Al Gore’s plan, perhaps the next one will have a slight green tinge to it.
