Thank you for this example. Exactly what I needed!
One question though: Do you remember where you got this
jquery.tipsy.jsfrom?I have problems with wrong tooltip positions when using tipsy's latest release (1.0.0a) as well as the current master-branch from https://github.com/jaz303/tipsy. Using the file from you gist fixes it. Did you apply any patches to it?
