Magnetic Blocks Puzzle

The coloured blocks attract blocks of the same colour.
Aim: move the blocks around so that the blocks of each colour are stuck together.
Navigation: Use the NSEW buttons or from your keyboard use NSEW keys or the cursor move keys to tilt the tray.
Pieces, when moving, will travel as far as they can before coming to rest. This is a property of each of these puzzles, but I may introduce some which behave differently, so look out!
