hey! i had this tutorial in my mind for a long time, but i thought about it as "Blob mesh". i thought that it's useless but it looks like someone really needs it. and Lava Lamp sounds much better so be ready. the tutorial is coming.
the basic idea is to draw the blobs, apply some turbulence if you wish, blur them quite a bit, and then apply alpha levels on the adjustment layer above them.
this may be not the exact recipe since i don't remember how i did it when i was planning the tutorial, but since someone needs to know, i'm sure to check it out and record a new tut.
good luck.
cheers.
