A toy called StellarWindows from Japanese company Fairy Devices can give you a peek of outer space. The toy, game, or educational system (depending on how you view it as) comes in the form of a CD software that you need to install on your tablet or notebook PC and a USB dongle that contains the compass and an accelerometer. To use, you would need to hold up your tablet or notebook PC to the sky; the USB dongle tells the software where your computer is pointing and the software shows you the corresponding 3D view of the sky object selected.

While it's ideal to use StellarWindows on portable computers so you can easily move it around while positioning it against the sky, the software can also be installed on desktops. The system comes off a bit pricey at $240, but for those really interested in space, I imagine the price is well worth it.
