"So much to undo and so little time."
Hence, Project Undo.

The idea: spread the concept of Undo.
Wear an Undo shirt to advertise the message.
I am not selling Undo shirts, I am making them. I will make you one.
Send me a shirt of your choosing and the cost of return postage, and I will hand print your Undo shirt (with black textile ink) and mail it back to you.
Wear your shirt to help sow the seeds of Undo.
What would you do if you could undo what you did?
