This month we're making a slight change in our photo challenge.

We have been so impressed with your participation that we have decided to end each challenge with a poll. The poll will be added to the challenge threads at the end of each month and be open the first week of the next month. The photographer that gets the most votes in the poll will be awarded with a free SitePoint eBook of his or her choice.

In case of a tie, the winner will be decided by the content team.

Because we are making this slight change in the challenge, we thought we'd kick it off with a "slight change" challenge.

Please post your photos of things that will or have changed over time. Please -- no photos of people.
