Your first photo is of something that shows the current time! Document when you started the blitz. You could screenshot this page as it shows the time.
In the next 20 minutes, try to capture as many of the photo ideas listed as you can.
Take another photo of a timepiece that shows the time you stopped. It should be twenty minutes since step 1, right?
Clicking on items will toggle the background colour so you can keep track.
The page will use local storage so the list will stay even if you go away from the page and come back. After you have loaded it the first time you will be able to use the app offline.
This webpage just generates a random set of 5 tasks from a list for 20 Minute Photo Challenge: ds106 Photoblitz - CogDogBlog.
The photo ideas are lifted from Alan's post, the ds106 daily create and the, now discontinued, Daily Shoot site.
Clicking the button above will give you a html version of the list you could paste into a blog post.
