I cant find a link between your design and the whole concept of Indigo... The current logo has an I seen through a glass sphere showing the most basic aspects of light simulation, Maxwell has a sinusoidal curve design to symbolize a light-wave which rendering is all about, etc. I think if we
have to change the logo, it should go along these lines, and have a minimalistic font, the one you chose is a bit heavy. I'll think about something, but im not a logo designer lol
EDIT: And it has to be a simple design, that could be overlaid on renders, like on your example.
