Caligari gave away Truespace version.3 for free a few years ago
I get spam from them in my email just about every day. I get spam telling me if they have a special price for version 6. Then I get spam telling me if the special only has a few more days left. Then I get spam telling me if the special is coming to an end. A few days later I get spam telling me if they have a 'limited time offer' bundle that includes free training.
