The house where I live is filled with art.

Most of it was there before I moved in,

and I've never met most of the artists.

I'm moving out very soon, so I decided to make a contribution to the house... a parting gift, I suppose.
Basically, I painted blue rectangles in the hallway.
This is what they look like:

Yes, I know... They don't even look like murals.
In fact, they're just blue rectangles, and most of the people walking by won't give them a second thought.
They're more than that to me, though...
I think of them as frames for future paintings.
When I walk through the hallway, I slide my fingertips across them, wondering when someone will see them as canvases, and I'm looking forward to this stranger's inspiration.
And this day will definitely come.
Some day, some stranger will paint on my blue rectangles.
It will make me a little bit sad, because they'll no longer be how I made them, with endless possibilities.
Instead, they'll be the platform for one person's art...
When that day comes, I think I'll be ready for it, but not today.
Today, the platform itself is art.
But to you, they might be just rectangles, so it's time to finish my postmodern rambling...
I painted blue rectangles in my house.
I spent an afternoon and an evening on them.
To most people, they are just rectangles.
But to someone, they will be frames.
One day, these frames will hold that person's art,
But for now, the frames are the art.
