Daz 3D the developers behind Bryce have a special promotion currently running whereby their major titles are totally free.
Theoretically a saving of nearly $900.
I've used Bryce for years, it's a great way to begin 3D modelling.
Yup this is a great selection of 3D applications being offered for FREE!! for a limited time, I suggest everyone grab them NOW, cause you never know you might need them later on for ..erm something :)
