Ok, I know it's a bit early as the Program does not come out (in the US) until Thursday but this is something I am looking forward to.
Colors! was original a Homebrew aplication on the DS but became so imensely popular they Nintendo approched the creators to make a program for the 3DS' eShop. I guess this is one case where modding a nintendo system paid off.
How Colors!3D works.
It's basically set up like any PC art program with different layers and color pallets to use but on top of the diffrent layers per-sheet there are also diffrent layers per depth. With Colors!3D 5 layers all together. Each layer (excluding the furthest base back layer) you can adjust the depth of slightly.
Once you are done with you picture you can then save it to the 3DS as you would a regular picture or upload it to the Colors! website. This also allows you to share the picture Via Swapnotes. So if anyone else gets it I would love to see some of your art.
Any ways here is a YouTube video (a quick one in 2d) of it.
I wonder how many Pokemon 3D pictures will be done the first week alone?
