i saw a cafe that they'll read your fortune for you for $10, which seems like it might suck for the barista if they're short staffed, so here's my idea
you get a capsule machine with those plastic multicolor alien toys, and you put a sign up for each color like "GREEN = plague, misfortune, avarice; YELLOW = wealth, warmth, hospitality, diuretics"
then you add a brief little text in each capsule like "someone you know is very horny right now. lend your flushed friend a hand" or "watch the skies; the birds bring tithings. follow them."
and then the idea is you apply your alien color theme to the fortune and also you get a little plastic alien
