From NASA's always-amazing Astronomy Picture of the Day:
Now, as part of the planned upgrade of the International Space Station, an Expedition 18 astronaut has upgraded her own head. The Human Extended Analog Device 9000 was attached with only minor delays, making the astronaut's remaining spacewalks over 40 percent more efficient. With the HEAD 9000 attached, an astronaut can now directly access 4 Gigabytes of computer flash memory with their own brain, perform complex mathematics by "directed thinking", and play a pre-installed game of Tetris at no additional charge.
