Make 16 instantly obvious
16 circles — 4 green, 4 yellow, 4 red, 4 blue — scattered randomly. Drag them into an arrangement where anyone could instantly see there are 16.
There's no single right answer but some arrangements will let your eye take in all 16 in a single glance, while others will make you count them one by one.
