Two thoughts come to mind:
- My 3 year old son loves playing World of Goo with me. He can't solve problems yet, but I can see he is soaking up loads of information.
- Have a go with Alice. My son is too young to try this, but once he is older we'll give it a go if he is keen. FWIW I learnt about this program after watching The Last Lecuture by Randy Pausch (R.I.P)
