Being the bartender sounds fun, until you realize you have to crack a cocktail recipe book. Engineering to the rescue! This drawing -- originally used to test plotters -- was converted into an AutoCAD file by Florian Römhild, who later colorized it. You can see it contains all the info needed to mix classic drinks -- the volume of each ingredient (with a handy key), type of glass, garnish and whether to shake or stir. It also lets wannabe drink-slingers visualize each libation at a glance. The best part? You can stick it up on your bar for reference and a touch of geek chic. For a PDF version, hit the source.
