zizifus (also known as jujube) is a plant, dried fruits of which I like really much. and sound of its name is kinda funny too. i was thinking during weekend if it will be a good company name, and tried to image how it will sound when i will say: I'm working at Zizifus. For Germans it will be a tricky word to pronounce - tzitzifuz.
I'm still not convinced myself but as a draft name it is good. Maybe I should call some project instead.
