If you're good in standing on one hand you should try to do one and then turning 180° or 360°. and later perhaps you can practice to keep on turning. 180° or 360° looks verry cool already and isn't as hard as it looks. Most breakdance moves look easier than they are, this one is not easy but not as hard as the real big ones.

Also here's a noce battle in which one of the guys does one (he turns longer than 360° tough, quite a bit even.)
