Science Fiction mini library display

A while ago I randomly won some Star Trek stuff - a duvet set, t-shirt and a mouse and mouse-mat. Now, I'm no sci-fi fan, so wanted to use it as prizes.

I set up a mini display, again nothing fancy, on a small trolley I have. It is advertising a competition where if a student takes a sci-fi book out (my books are arranged in genres, see here and here) they get entered into a raffle.
