^^ A single delayed axel is a gorgeous move, but it doesn't have a high leg kick.
Ben Jalovick's cool move seems to come closest to resembling the 540. John Misha Petkovich's flying axel sit spin came immediately to my mind, as already cited by
@pETEs (Sasha Fan). JMP's great feats were discussed in a thread here about a year or so ago, with many oohs and ahhs. In addition, although it's not exactly like the 540, Brian Boitano's amazing death drop was always a wow in his programs.
Boitano demonstrates it in this video at 1:40:

Ballet and figure skating both incorporate amazing athletic feats. Each discipline has its limitations based on the surface and lower extremity equipment (stage floor that has some give vs unforgiving hard ice; and bare feet or ballet slippers vs rather unyielding skate boots). As far as your reference to "looking pretty"
@Vash01: figure skating is sport and art -- the aesthetics are important or we wouldn't be discussing aesthetics in so many threads. It's not about looking 'pretty' though. It's about hard work and making the impossible possible while looking effortless doing so, and of course strategizing to garner those necessary points. Ballet is even more about performance art, but you can't come close to doing that either without a strong, fit, limber body combined with talent.
Kung fu is an ancient discipline which is more about mind over matter. You have to be physically fit, but also mentally and spiritually strong. It's described as "a practice that requires patience, energy and time..." In that sense, the same can surely be said about ballet and figure skating.
