I gave my 9 year old son the simple task of writing thank you cards for the birthday gifts he received last month and he turned the task into a major project by choosing to paint each gift giver their card instead. (The apple doesn't fall far from the tree.)
Once he finished the thank yous, he moved on to snowflakes in a watercolor resist technique. He informed me he plans to sell these at the Christmas Bazaar where I will be selling my art as well. I fear he may run me out of business!
