On iPad, starting portrait and rotating landscape redraws but same size (too small). Starting landscape and rotating portrait tries to redraw same size (too large) but breaks layout, pushing text below image.
I feel as though portrait mode on iPad might look better with white box below the otherwise extremely tiny image.
Looks fantastic on desktop Safari.
If you start with it in either orientation it should be fine though.
Also if you do end up using it, then feel free to submit a PR to the readme to add your website.
