Organica is very privative and easy. It has 4 viewports, front/side/top and one viewport that shows finished product. It's got a bunch of premade shapes (ball square cylindar and a host of other shapes. You drop one of the shapes into the view port, add another shape or the same shape, whatever, the closer they are to each other, the more "attracted" they become. You can deform the shapes one at a time. You can export in different formats (not obj) The program lacks a lot of frills (ortho mode for one). Here's a link. The program is not as great as they make it out to be, but it works great for making irregular organic formed objects. http://coolfun.com/INFO/PRODUCTS/Organica/organica.html It's got a special price: $150, (yeah, specially priced for the last 2 years) Davo
