Is your sight good enough to see what's hidden in this red dot?

This red dot is the latest internet ‘test’ to do the rounds.

See anything?

Contained within the dot is an illustration, but some people can’t seem to see it.

And the degree to which those who can varies.

Some people see – drum roll – the outline of a horse.

Others see a horse complete with mane, saddle, and grass by its feet.
