How do I enable the 'wobbly windows' effect in LL2.8?

[pauloz]

I've tried Compiz on LL previously and honestly, I'm not a fan of it as it's very buggy. The effects do not always work but my biggest gripe is that quite often LL will not restart properly (I get a blank screen) after I suspend or hibernate. The same problem occurs with Compton. What we get out of the box from Jerry is the biggest strength of LL. Not worth tampering with useless effects IMHO
