Ok then here is a tutorial for Mandelbulb 3D on how to make the "Tuber" pieces I've been doing lately. Hope you have fun and let me know if you have any trouble. It's a zipped html file so unzip, click on the html file and have at it!
The version linked to below is a new version. The version the tut was written with is no longer available as far as I know. So some of the interface will be slightly different. Note me if you have trouble with it.
