Designing For Children

[MetalMilitia]

So I have to make an educational Flash website aimed at 5-7 year olds but I have no idea what would appeal to them besides standard HCI guidelines (layout principles etc.) .

I'm thinking that a site resembling a note pad with pencil writing and kids pictures etc on would be best. Somewhat cliche but it's about the only think I can get looking stylish while remaining accessible to young kids.

Anyone have any experience in this kind of thing to offer some pointers?

Thanks.
