People have often asked over the years where I get my cool space themed desktop patterns.
Astronomy Picture of the Day is the place to go.
They post some of the best space pictures and they are usually HUGE, so you can actually make a decent desktop pattern for a big monitor with them.
And, today, APOD is 15 years old. There are a few of my tax dollars I feel pretty good about.
And the 15th anniversary picture is a composite made up of pictures posted over the life of the project.
