We've all seen motivational posters. Most of us have seen demotivational posters. It is somewhat of a hobby of some people to create them
themselves. You find a suitable powerpoint template, hunt google image search for a fitting image and paste in your funny sentence. Oh
and pick a color that matches the image you picked. A lot of work. This little web app automates all the stuff. Plus it gets you
bookmarkable urls for your creation.
The images are just from the top search results (it likes the ones with a nice landscape ratio better). They're quite likely copyrighted,
so don't go publishing other peoples work before making sure they're ok with it.
