I was messing around with the pics I had one day and I inverted their colors. They looked awesome and I have to show you.
Here is the PS3 after the colors were inverted.
Here's the Xbox 360 inverted.
Here's the PSP inverted.
Here's the DS inverted.
Here's the Dreamcast inverted
I don't have it on this page but I gave it a page of it's own, check out the Nintendo Revolution if you want to see it inverted.
