Watching the style evolution over the years, you can see that the shots get crisper, brighter, and more fluid (almost to the point that the "stop" of stop motion isn't even noticed). "Fresh Guacamole" displays refined technical skill along with PES' usual sense of humor (diced onions, anyone?). My favorite part of this video, however, is the rich soundscape that brings the images to life. Watch it once, then play it in the background while just listening to the slices and crunches and whacks (especially enjoyable if you're ASMR). Just like being in mom's kitchen, no?
