  My 4 year old loves assembling these somewhat randomly (usually while I'm playing with them.) For her, the most interesting behaviors are when she seriously stresses a circuit by adding jitter - like forcing a servo to a new position. She'll sit there and I can tell she's trying to figure out why what she's doing has an effect on an unrelated part of the system.
