I'm sure you're all familiar with pattern recognition puzzles where you have to find the next picture in a sequence. Well, I’m completely stumped on this one… Can you help?
There is a sequence of pictures in the top row of this image. Which of the four options in the row below completes the sequence by filling the box labelled with a question mark?
Which of the four options should replace the question mark?
The graph in each square represents an object. What might this object be, and how might the colours be important?
This is my own problem, with a well-defined solution. It is an inherently visual puzzle; the colours of the dots are listed in a pastebin. Note the precise details of the lines (length/straight vs. curved) and dots (precise coordinates, RGB values) are not required; some of the presentation is aesthetic.
