Opps! Sorry for my late reply but it seems to be working now! Just the styling of the blob seems to be a bit off due to the width of the menu. Well done!
Hi petergus.
Yep, i managed to get a lavalamp navigation up and running for a video production site – http://www.konclave.com
This is the tutorial I used for the coding of the menu into WordPress

Lastly, here is the original tutorial for SpasticNav – http://net.tutsplus.com/tutorials/html-css-techniques/how-to-build-a-lava-lamp-style-navigation-menu/
I re-styled the menu in a different style from the tutorial. If you would like to use what i did, do let me know
Have fun and message me if you run into any trouble. =)
