Leprechaun - GO!

Here's an idea for a phone app - Leprechaun Go! Similar to Pokemon Go but instead of having to find Pokemon balls the goal is to find Leprechauns that are released in participating bars. The reward for finding and catching a Leprechaun would be a free beer!

Someone like Guinness or Budweiser could sponsor it and tie into Saint Patrick's Day festivities. Say release a Leprechaun randomly every half-hour over a geographic area - like a city.

Think this would be a hit. If someone wants to write the code, sell the idea to the beer company - I'd be willing to split the profits.
