Also called a camera obscura, a pinhole viewer is a imaging method that exploits the fact that all light travelling through a pinhole is in focus. Poke a hole in a cardboard box, and hold the hole up to the sun. The light that passes through will project an image that you can view safely.

Google camera obscura for design ideas. They're really neat and easy to make.

From one of liam's replies:

residents push back strong against low-income housing development in their communities making it more difficult for new homes to be built.

This seems like a cornerstone of the affordable housing issues where I live. How exactly is that push back organized in California, why is it effective, are the mechanisms of resistance to low income development similar in the rest of the US, and what can rent burdened individuals do to help combat it? What kind of policies could address this pushback?
