It’s a neat short, with some nice animation and cool music (which for some reason reminds me of Super Metroid). The use of a LEGO train to transition from live-action to stop-motion is particularly inspired — though Heavy Visuals’ work always seems to exist in some interesting middle ground between live-action and stop-motion. Apart from some minor technical failings (mostly color keying artifacts), it’s pretty solid.
Plus, it’s got graham crackers. Check it out, before the whole city is destroyed!
