As a thought, what about a beer ID unit. A light and sensor to check the light transmission of the beer to detect mild pales from dark lagers, and calibrated for each step in between and so forth. Add in a probe to test for conduction, a thermister to check temp. (is it right for drinking), surface sound detector (small mic element and a surface screen to detect noise of bubbles bursting on the surface,(has the beer gone flat). You can even add in actual sensor elements to detect beer motion within the glass, and it there is none, it spins to stir he beer for a more oxygenated beverage. Let your humor and your mind have free run. :twisted:
