Pattern
You walk up to a tree and put dynamite on it. Then you set it off. BOOM. It explodes, but doesn't do what you'd expect. Instead of blowing the tree up, it blasts a very beautiful pattern into the side of it as well as the ground around it.
Think about what pattern it might be. Is it a checkered pattern? Something more complicated and beautiful? Whatever it is, think of something that really impresses you.

The pattern is so beautiful that you want to put it on your garage (がら). So, you do.
Imagine painting your garage with the pattern you imagined earlier.
