When I first saw Caligari on Amiga I was really blown away… imagine, over 20 years ago now, and it had full-window 3D perspective editing, drawing objects in solid even. To my knowledge this was the first editor dropping the traditional 4-split view, which was a big inspiration for me. In the years that passed I only occasionally looked at what trueSpace did, but I know they kept exploring innovative 3D editing, moving user input to the 3D window where ever possible. They even introduced integrated collaborative workflow via internet in their latest release. Hats off to the Caligari team, and especially to founder Roman Ormandy. You've written a piece of CG history nobody will forget. I know how it is to be locked up by corporate demands, and the tragedy of seeing your baby slip away in other hands… Blender fortunately escaped this route, and hopefully Roman will – in a few months when the dust has settled – find the method to make Microsoft accept a community buy-out too. Reading trueSpace forums, there's a massive and very devoted community there, don't underestimate their powers!
