Monday Happenings

Beer Tricks

-- OnLatte is a Cambridge company that has figured out how to print images in the frothy head of various liquids. More commonly applied to coffee, the company's technology has obvious implications for beer drinkers. Join the company tonight as it prints the pictures of people onto pints of Guinness. Don't forget to wear your beer goggles. The Field, 20 Prospect St., Cambridge, 6:30 p.m. No admission.

Punk Rock

-- Boston has a storied history of punk rock, and it's never too late to act like you know. Pulp 45, Zip Tie Handcuffs, and Ghouls Night Out each represent different veins in the punk rock circulatory system. Middle East Upstairs, 472 Mass. Ave., Cambrige, 9 p.m. $8.
