Maybe the tone was a little off-the-cuff, but mjolk has a valid point. You can't implement the idea without some sort of coding. Design alone doesn't cut it, and I say that as someone that has a lot of respect for designers.

I have a design background, I agree with mjolk's point as well.

Designers are fine, but don't tell me that a render is nearly as useful as a prototype.

Please though, if you disagree with me, open a dialogue. As an technology investor, who would you rather fund?
