Monsters working on a house of cards

These monsters are working on a house of cards, an experience similar to working on a code-base that has not been tended to appropriately over the years! This is a slide from my “Algorithms in CSS” talk.

A red monster on top of a yellow monster positioning some cards at the top of a teetering stack of playing cards. The yellow monster is saying "Omg careful". They both look very nervous. On the right side of the image "House of Cards" is written.
