This design has been stolen from me a number of times and has made its way around the internet, but I finally have it in my store now for anyone who is interested in purchasing it at TeeTurtle.com ([link])
I know this is an old piece and I am commenting way later but what the heck. Anyway. Yeah but he said this has been stolen from him...but I do believe the concept in the design is stolen from Pink Floyd's album "Dark Side of the Moon". So who really is stealing from who? Be more original and create your own design, your own art and concept instead of copying others. I mean come on, you went the same direction in the light transition to color spectrum, you laid it on a black background, come on now. Pink Floyd or the actual designer of the album cover by Storm Thorgerson may be flattered I suppose but still. In my opinion this is a rip.
The idea of light hitting a prism and reflecting into colors is owned by no one. Pink Floyd made this certain image popular, yes, but the concept of the image was used many times before because it is a picture example of light turning into color.
