Ulterior Motive

This is an amazing structure.

My first touch took quite some time and ended in 419 steps. I will keep looking. Really a great one!

EDIT: I later found a 370+, then a 339, then a 305 and now a 295.
Will keep looking.

EDIT 2: Got a 275, now. But can't find 
shorter, atm. Will be back.

EDIT 3 (next morning): Today I found 253, almost right away. But now stuck again. Will be back!

Panacea

Such an absurd, finely-tuned machanism, this is an incredible level all-around! Hard to complete, harder to optimize, all with individually simple bits of logic that work together to make an impressive whole.
