The application may take a while to launch (5--15 seconds) as the graphics are rendered.

The coffee shop puzzle is a variation of a classic computer science problem.  Don't mention which one here to keep it interesting.    Some people can think through the problem and solve it in seconds.  Others will remain baffled for hours.  Ideally, work out a strategy in your mind and carefully execute it.  Don't rely on paper and certainly don't code up a program to solve for you.  Post a screen shot if you're the first to solve it.  Good luck!   

Awesome graphics! =D
I don't know what strategy I'm supposed to use, but I solved it the second time I tried it. The first time, I got the smallest cup to the center tile instead.

Fun

Yeah very nice graphics indeed, and a nice variation of the original 'computer science problem'.    I actually wrote a java applet version last year (so could complete quite easily) but this looks loads nicer.
If I remember correctly the minimum number of moves is 2^noOfCups-1, in this case 31.  If you have any free space you may consider allowing the option to choose the no. of cups (3 to 7,  7 achievable in 127 moves for the extremely bored amongst us!).
