# AlguaBeep
Une expérimentation hasardeuse pour traduire des images de webcam
en sons qui déchirent les oreilles, mais qui sont bio-dégradables.
C'est une expérimentation hasardeuse pour traduire des images de webcam
en sons qui déchirent les oreilles, mais qui sont relativement
inoffensifs.
Pour le moment, il n'y a pas de procédure d'installation, il faut
donc lancer le binaire à partir du répertoire de dèv :
`~/Devel/DD2-monitor/Beep/alguabeep [options]`, ce qui implique
de ne pas aller mettre la grouille dans ce coin-là.
Ensuite, pour apprécier pleinement la kitchitude (assumée) de l'affichage
numérique de la machinerie en action, il faut un `xterm` en 150 caractères
de large, et une toute petite fonte.
## Usage
```
available options:
-d /dev/? select video device
-I take pictures
-K set the K parameter
