Cogs, Cogs, Gears!

When you perfectly align them on their notched edges they move like clockwork! Cogs! Gears! They help us move lots of things. From compact objects like watches to huge factories, these tiny little gears together have a huge potential for great stuff! Illustrations featuring them often have machinery ranging from the near-future to the retro style, old fashioned machinery... allowing for a lot of different types of motifs!
Today's Spotlight is all about the illustrations that feature these cogs and gears!
