Paper Football Lite for iPhone
Paper Football Lite by Jirbo is a fun little app that lets you relive your glory days on the paper football gridiron, aka the school lunch table. You take turns pushing a little paper football across a table, attempting to land the football on the edge of the table closest to your opponent.
