prout: nuage de particules quand on pète!

Voici la fontionalité tant attendue et merveilleuse! Le prout de
princesse. Mesdammes et messieurs vous n'allez pas en croire vos
narines ni vos panflet pantouflés. La princesse en plus de son retour
haptique à base de vibreur dans la manette vous offre également une
prestation graphique des plus prestigieuse, à savoir, des particules! Et
oui vous avez bien lu! Vous chez public singulier qui passe trop de
temps à lires les messages de commits. La princesse vous communique la
durée et la direction des dash proutés grâce à cette belle trainée
verdâtre. Vous m'en direz des nouvelles!
