No longer a janitor, but still elbow-deep in toilets.
My greatest ideas come as I'm nearly asleep.
I wake myself up to write them down.
They fade away as I wake up.
I try to go back to sleep.
More ideas come.
Following [2Fries] advice, my top ten (personal preference, not by score):
Off the Wall Prostheses
Custom Cooled Theatre
Roadtrip Soundtrack Radio
Interstate Solar Farm
Science Fair for Grownups
Fully Baked Engine
That last one is actually one of my most poorly received ideas, but is the one that I would really enjoy giving a shot at making. Perhaps that's only because it's the one that I could feasibly do with nothing more than a castoff lawnmower engine and some parts laying about.
