In last months curiosity box I received gellballs. Tiny little balls of about 1 to 2 mm, that you drop in water and they grow till 300 times their size (which is slightly larger than a marble) if you take all three dimensions into account. They look awesome, so I took a picture, and enhanced the contrast, highlights, shadows, clarity and luminosity. The light one is the original, the dark one is the end result.
