Webcam as Memex
I am intrigued by Vannevar Bush's 1945 idea of a memex, a "lifetime store of everything". I wish I had a device built into my eyeglasses that recorded everything I see and hear, everything I type (for instant retrieval later), every website I visit, every email, every phone call I receive. It's often useful to be able to go into the past and recall what you were doing, or retrieve a document or email from the past. And it's just fun to see pictures from a week ago, a year ago, a decade ago.
Well I don't have a wearable memex, so I've set up the next best thing which is a webcam that takes my picture automatically every 6 hours. It reminds me of Mena Trott's project to take a picture of herself every day for the rest of her life. Or Project 365, in which you snap a photo every day. The beauty of this setup is that it's done automatically, so I don't need to remember to do it.
