Temporary extravagant follies of a young architect...
There was always something dangling from the balcony, or his bedroom walls ... and the car. When he was about 8, he had created all these electrical wiring systems that made sounds and lighting effects and needed a place to use them, so he built a wooden case then kept adding to it until it turned into a robot that was taller and heavier than him. He has about 10 projects going, and he feels there is always room from improvement, so they may either never be finished or be dismantled in a disapproving reaction.
If I remember correctly, his room is sectioned into the following categories: nautical, retro, neon, letter S, Minecraft, Dr. Who, acoustic guitars, electric guitars, hats, and ties. There is no room for socks or shoes so these stay outdoors even in the rain.
