WARNING: This isn't a game. Don't rate it as such.
It's meant as a showpiece for designers/artists who want to put their content in it.
Features include standard and big tiles, scrolling to new "Collections" or "gaps", enlarging pictures by clicking, growing a picture on mouseover, non-clickable info tiles which show text (and have hex-colors applicable), info panels on picture tiles (when enlarged).
The pictures in the GUI here are just samples.
Anyways, I worked on this for a few days. Thought it might be worth sharing. Based it off Windows 8 Developers beta (slightly).
Preloader is just a ghetto little thing. I'll update it eventually.
