As an old Yiddish proverb says,
The world consists of cogs: one depends on the other.
Di velt iz a hekeleh: ainer darf tsum anderen.
And on the wall, Hebrew idioms using the word "wheel," e.g. "to reinvent the wheel" and "If Grandma had wheels ...."
I found these in a play area for kids in the antique automobile museum at the Omer Open Museum and Industrial Park.
In future posts you will see their nice sculpture garden, a photography exhibit, friendly cats, and of course the old cars.
