An analemma is the figure “8″ loop that results when one observes the position of the sun at the same time during the day over the course of a year. Due to the earth’s tilt about its axis (23.45°) and its elliptical orbit about the sun, the location of the sun is not constant from day to day when observed at the same time on each day over the course of a full year. Furthermore, this loop will be inclined at different angles depending on one’s geographical latitude.

I like that first one, it looks like a butthole.

The Visual Patterns of Audio Frequencies Seen through Vibrating Sand
Youtube user Brusspup (previously here and here) who often explores the intersection between art and science just released this new video featuring the Chladni plate experiment. First a black metal plate is attached to a tone generator and then sand is poured on the plate. As the speaker is cycled through various frequencies the sand naturally gravitates to the area where the least amount of vibration occurs causing fascinating geometric patterns to emerge. There’s actually a mathematical law that determines how each shape will form, the higher the frequency the more complex the pattern.
