Constraints can shape art. A good example is the band “The White Stripes.” The very limited drum skills Meg White brought to the table actually created a unique and successful sound.
Another great example is this piece called “Kitchen Crash” on Basilike Pappa’s amazing blog “Silent Hour.” Each sentence contains eight words, which match the number of letters in the word “omelette.” These self-imposed constraints shaped and informed the art.
