Thats the thing - Its hard for me to give you an exact resource - since the first thing I ever coded was a visual, using logo, when I was a wee lad. Over time I just kinda picked stuff up here and there, mostly by reading code that others have done. For a long time I was obsessed with coding straight up pixels, and writing putpixel routines. Even lots of the html5/canvas stuff I do these days is just getting the context imagedata buffer and writing straight to that. It was a totally organic process with zero structure.

So if I were going to start again from scratch, I would probably do the following:

      - Choose one platform to target (HTML5/Canvas, WebGL, OpenGL, DirectX, etc)
      - Pick up a book and learn the basics of that platform, and do the exercises
      - Learn what you can about the APIs and start playing around.
      - Fractals and cellular automata are always fun - you can find Mandlebrot and game of life examples in pretty much any language.
      - Think of something in your head and try to make it happen!
      - Add interaction
      - Rinse and repeat
