If you have an iPhone or iPod Touch, I highly recommend the app AutoStitch for creating some pretty impressive panoramics. It does an amazing job with just 2 or 3 photos, and is still impressive when you point it at about a dozen. That's how I created the above shot of my cube.
Update: Latest AutoStitch versions allow you to crop within the app before saving. This makes for a much cleaner panorama. Can't recommend the app enough.
