IOTD: The Tube

The Tube, by Johan Halmén

This is a simple demo I did. An image is drawn along a Bezier path. I kind of got hypnotized by the tube while watching it evolve and had this idea: the image could scroll to the left while the tip of the tube would write text using a script type font. We have this huge 40 inch monitor (640x480) at school and I thought of creating something visually appealing for it. If someone's interested in the code, I'll put it here (150 lines).

That is seriously neat. what if you rotated the image slowly while it travels the bezier? - jhuuskon

Thought of that. The problem is that the shading effect comes from the image I blit. If I rotate it, the light direction rotates, too. I should use an image with only a texture and a separate alpha channel. First I would rotate, then apply the alpha channel as a shader, then blit to the screen. - Johan Halmén

There was something like this in the Organic Art screensaver from the Win 98 Plus! pack... except that it had multiple objects spinning around, and the screen was mirrored, I think. Anyway - that's pretty cool! You should make a screensaver out of it. - mystiscool
