Page background generated with my pen.
In-game textures and levels also whole generated. Most textures just a Red,Green,Blue,invR,invG,invB,Opaque-border-to-show-transparent with or without rects and color marks over it. (couple of FORs iterating over colors and options to fill html5 canvas)
Terrain is a Perlin noise and all other just my own reinvented(But no so different from well known) algorithms...
