Electromagnetics demo

I actually forgot what exactly I did. Still a nice looking demo or something like that. 3D might be delayed by a bit. Want to simulate some strings now. Besides, I still refer to OpenGL as 'That stuff I use to draw lines'. Getting camera movement is going to need both SDL and OpenGL to do their thing, which is going to take lots of trial and error to do. I mean considering the hack I use currently to display TTF text(SERIOUSLY, I don't want to spawn an entire texture, just let me draw stuff to renderer, k?), it's going to take some serious workarounds.
