Comments from TAs

Nice work. And good job taking advantage of LEGO components to get things moving -- they can be a great resource for building mechanical projects! It would be interesting to consider augmenting the orbiter with other types of inputs (LEDs, piezo sounds, etc.). Or, you might want to consider the "playing use case" for the LEGOs. One of the best things about LEGOs is that children can play with the kits after you build things with them. What new kinds of creative play might a moving space orbiter (or other interactive components) enable?
