Eep.  Wasn’t expecting a question about him yet. lol. I guess one hobby would be making orrey ( orreries ?)   these things i guess in some odd ode to Cybertron and moons before scrap hit the fan

he always made small ones and often with blue crystals that would hum (differently) depending on their rotations

one of Aims’s ultimate goals/hobby dreams was to make a very very large orrey garden decorated with the crystals.
