For anyone looking to use the polygon word wrap feature as in the demo on the Github page with the Eiffel Tower, take a look at its responsive behavior before you make that post. As you shrink the window down on jack.ventures, some text can be cut off, or no longer show up on a clear portion of the image like a wall.
This isn't a bug with the software so much as a flaw with the magazine "words on image clearing" style layout that doesn't translate perfectly to the web medium.
So if you resize the window and reload the page it should fit everything correctly again.
A rough design pattern I've seen is
Desktop resolutions: use layout in terms percent. For instance: left side of text begins at 50% of image width.
Tablet and mobile resolutions: fixed layouts for each resolution supported.
My philosophy for mobile resolutions is to just deliver the desktop experience. The text will be tiny yes, but you can just pinch to zoom. Sites that lock down the zoom kind of annoy me personally so that's why I did it that way.
The second theme does have media queries for mobile sizes though, since it doesn't rely on the text being in a particular spot to be readable.
