Huh?

goro-fujita-huh

How does the caveman feel? How do you know?
What is he thinking? Has he ever seen a drone before?
Where did the drone come from?
Who is controlling it?
Has the drone gone back in time, or has the caveman gone ahead? How did this happen?
Write a story based on this image. What other periods of time could the drone capture, or could the caveman visit?
