Peg Colour Match

What to do with a left over spring roll container? I can't be the only one who sees a piece of "rubbish" and thinks that may be useful, then has nothing to do with it? I had to think of something quick otherwise this "useful" piece of trash was going in the recycle bin for melting. So...

Place coloured card (you could also use patterned scrap book paper, I regretted not doing this) into each of the compartments.
Collect a peg for each of the interior walls. Stick a piece of card to each side of the pegs corresponding to the two adjacent coloured compartments of the wall that the peg is attached to e.g. the peg on the bottom right of this picture would have a purple and a green side.

This is a complex twist on basic colour matching, of course you could use the compartments for basic sorting also. I have made the card removable so that the can be taken out a put back into the correct places to ensure all pegs can be matched to colours, of course this is for extreme complex problem solving.
