I did that same thing one clear beautiful morning in a 767. Took off from KSEA headed for KATL and asked ATC for a VFR climb - he knew what I meant. I leveled off about 11-12,000? and basically did a 360 pylon turn around Ranier, then continued on our way. No video on mine, but everyone appreciated the view. That part of the country has unmatched beauty on clear days.
