Found this simple craft idea from www.ActivityVillage.co.uk while I was surfing online. Not only it is simple, it would be great to use it for our playgroup. Do visit their site for more ideas.
Materials: Unwanted CD, CD-Rom or DVD Craft foam (in lots of different colours) PVA glue (white glue) Method 1. Cut the foam into squares or shapes. 2. Start of the middle, use different color foam and stick on the CD. 3. When completely dry, trim around the disk to leave a mosaic circle.
