Started another project a couple weeks ago to keep myself on task in terms of taking pictures. It's the 365 challenge, and the format of the website forces some discipline - they only allow one picture per day, and they keep stats on your progress - number of pics, number of days in a row, length of your current streak.
Of course there will be days when I want to post more, and days when I don't really want to post anything, and that's part of the challenge. You gotta post something or break your streak. Even on bad days I try to find something interesting, even if it's a macro of something lying around the apartment.
Anyway, this is one I was going to post but I had other shots that day I liked better (including the previous shot, after the storm).
