Thanks again Vincent:
Update I guess?
I don't have any screenshots, but I've figured out a neat way to recreate the SNES MegaDrive magic of 2D distortion effects.
I've made a heat wave effect which looks wonderful on most devices (OpenGL 1.x) . It's something usually used in the underwater areas of games. The screen begins to shake as if there's a good amount of heat or wavy water flowing.
I've made some other interesting effects as well, as well as perfect verlet rope and a pixelation distortion effect.
For the most part now, my use of 3D is going to be limited, 2D can be a crowd-pleaser if used right.
Can anyone here think of any unusual hardware effects for games? Something that may have been used in the past for older games?
There's also a Windows 8 App that will be in the store soon using SGDK2, it's something smaller that I've been working on, unrelated to this.

My mouse isn't working and the tablet is dead, so it's been on hold for a while.
