5 Numbers
A weird game with instructions in Japanese (I think), but actually a very simple concept. Click on each of the terminal things (the grey boxes), and use the clue to work out the five digit number. Type in the number, click "Lift", and away you go. If you get it right then the terminal will be replaced by bits of something else (I'm sure you'll work out what quite quickly).
I managed all but three fairly quickly, and have now managed all but the grey and black pattern puzzle (feel free to give me any hints!).
