From David Horvitz:

For all of 2009 I will send out small texts of simple instructional ideas through the mailing list below. I will also post screenshots of them on this tumblr page. These will not be done everyday, only when i feel like it and have access to the internet. But the attempt will be to do them everyday. You can also receive these in the postal mail.

All of these ideas can be seen as “open source.” I am relinquishing all control I may have over them on account of my position of thinking them up and publishing them here. In the act of sending them to you, you are granted, with absolutely no restrictions, full creative power over them. Feel free to realize, change, steal (you can’t steal something that is free!), publish, claim as your own, destroy, become influenced by (either because you like them, or because you hate them so much that they give you better ideas), appropriate, spray paint, or anything else with them. You do not need my permission for anything.
