Put together a collaborative art mosaic, which gives kids the chance to express themselves and there creative side without the fear of making errors. Allowing them to draw whatever THEY want with no restrictions.
Like the idea Jade, one think that i believe is a specifically strong point is that it is bringing people together which provokes social interaction, not just by the kids but the adults too. I think you could integrate an educational factor into the entertainment for the children. So by doing this the children are stimulated by the animations, but the animations have a underlying message to them. Im not saying detailed messages but that of which a young child could understand and retain
I think this is a very good idea Rong. I like the way you have chosen to go for something that is hands on as it stimulates the brain which ultimately can only do good in my view. Just a suggest, you can go for very known stickers like cars shapes but if you selected a specific community to implement it in, you could research into the communities background and go for more cultural related stickers.
I really like the idea here, I think you should maybe look into making a way to allow interaction between child and parent through the radio programme though, I say this because at an early age I think the bond between parent and child should be encouraged as much as possible and they would be in there comfort zones more which i think would allow them to develop better
