(i was supposed to publish this a week or so ago)
Here are examples of the rollovers. when u select a particular item on the desk, a block of colour will appear over it which will indicate its value. A chart will be on screen to show its value. the idea behind this is that the game player will score higher points according.

in the first snap, the colours range from a pink to a brighter red. the brighter is a more valuable item. i didnt like this thought because there is no real reason behind these colours. So i looked a poker chips and what value they represent. I know a lot of students like a bit of poker so this bared a bit more relevance!
