LSD is a very minimalist physics game. There’s a box. You can draw lines. And a dot falls. Your goal is to get the dot in the box. Simple, huh? All you have to do is draw lines in the right place to bounce the ball into the box. It’s doable, but maddening at times. Inertia is not your friend here- if you get your lines placed just right, that ball will bounce forever. As soon as you think you’re pretty good at it, you’ll be put in your place. -via Metafilter
