Documentation: requires jquery 1.5.1+

[DarrenCook]

The inline code (as of beta2) says: "jQuery 1.4.3+ is needed for this plugin to work"

However it does not work with 1.5.0 (in Firefox 11 or Chromium 17)
Lots of: Warning: Error in parsing value for '-moz-transform'. Declaration dropped.
The web site demo uses 1.6.2 and that works for me.

I tested and it works with all of 1.6.2, 1.6.1, 1.6, 1.5.2 and 1.5.1
(also, going forward, with 1.6.3, 1.6.4, 1.7, 1.7.1, 1.7.2)
It fails with 1.5.0, 1.4.4 and 1.4.3.

P.S. The 1.5.1 release notes are here, in case someone wants to work out why:
