re: Alternatives to traditional programming for aesthetics

Very similar mentality to you - I've done it all and nothing makes me feel better than a daily calisthenics program.

I start with a 1.5 mile run and start a routine of...
12 ring pullups
12 bodyweight squats
12 ring dips
12 bodyweight squats
12 ring rows
12 bodyweight squats
12 ring pushups
12 bodyweight squats

Then I reverse this back up, but max out the ring reps. Throw in some candlesticks or hanging leg raises at the end and I'm done with it all in 35 mins or so.

I've found with this I just don't accumulate the fatigue I would from any previous programs - ranging from marathon training to barbell regimes - but the aesthetic results are better.

K Boges and The Bioneer are awesome, it's amazing what simple and consstent can do.
