When people discuss the Raspberry Pi, the most common (and annoying) question is 'what can I do with it?' The answer is, of course, whatever the hell you want. (Actually the answer is usually create a media center but that's another story.) But the answer to that question should be use it to create a holograph of the Death Star and leave it on your mantlepiece for everyone to gawk at with envy. That's clearly the correct answer.
The above holograph was built by some enterprising human beings at The University Of Leeds. I'm not really sure how it works, or even how to describe how it works, but I thought you might like to take this opportunity to look at it and say 'wow'.
If you want to read more about how the thing was put together head here to the project's blog. Imbeciles like myself can just watch the video below!
