It sounds like Vasile and I at least sometimes think alike :-) I discovered this some years ago while cooking :-). Here the material I'd recommend is what we call Cornflour. I was thinking just a few days ago, after having encountered an ad for the "Monsterpod" camera support, that a contained cornflour mix MAY make a suitable mouldable base for a camera support. Able to be shaped but rigid against the camera weight. Quite how one would manage this in detail is "yet to be determined" :-) Russell -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
