dimples and bumps

Dimples & Bumps Exercise

By Steve Stockdale


This exercise simply asks you to look at the image to the right and answer this: What do you see at A - 3 dimples or 3 bumps, and what do you see at B, 1 dimple or 1 bump?

(a dimple appears to recede into the surface; a bump appears to protrude out of the surface)

After you've told yourself what you see, click here.
