|  no 4x4 and the head
Well, there is no 4x4FLI in it! Many people thought this on the party too.  It is "simple" char mode but the screen is 40x34.
And believe it or not but the last effect is not the classical 2D bumpmapping! All the effects in this demo is based on my method of rotation texture on a sphere. A special texture is the light. I map the points of the surface to the sphere accordint to their surface normals. I rotate the light texture on the sphere and color the points according to this mapping. The resolution is 160x100 and I use ordered dithering.
This is the theory. In this demo I approximate the surface normals with 512 uniformly distributed vectors and I calculate the light intensity for only 256 of them. I get the rest by averaging. The resolution is 160x100 but I use 4x2 blocks where the picture is not detailed too much.
And a very important trick: I use interlacing. I refresh the odd and even lines alternately.
Sorry for the bad english. I hope I was understandable.
