| ..."I am such a perfect & beautiful space-time|
| singularity, but those visits of my yapping |
| mother-in-law get onto my nerves like hell" |
| |
| - runs on DOSBox (best at 40000 cycles) |
| - assembles with Flat Assembler |
| |
| A quick port of an idea derived from a |
| GLSL shader code (See file 'shader_code'). |
| Then some bytes were left and I thought to |
| exploit Hellmood's pc speaker usage |
| introduction on www.sizecoding.org. |
| That gave some funny sounds and I chose a |
| product title that would make some sense out |
| of that ;-) ...äh...kind of... |
| |
| Sorry for no double buffering or vsync and |
| some other dirty tricks which may prevent it |
| to run on real hardware. The cycle setting at |
| 40000 is the only thing to be set in the |
| DOSBox settings. |
| |
| Cheers, |
| |
| Kuemmel |
| |
| Special thanks to HellMood and Sensenstahl |
| for continuous support and greetings to all |
| the others in the tiny intro coder world ! |
