Very slick looking, has that tech tv kind of feel to it which suits my business. The only thing I'd prefer to see is the G in the GR looking a little more like a G (extend the line in the middle just a little to the left). I think I have preference towards the 3d version. Other than that it will mostly be up to the opinions of those I poll about the logos which have been submitted. Good luck.
Thanks for your concepts. I want to clarify why your entry, #22, slipped a good amount in the rankings. I like this logo, but I was surprised to find few selected it as one of their favorite when I surveyed a group of people.
Just wanted to let you know why since it was a very good design and you've got a lot of talent and I appreciate your effort in this contest.
