while the effects are well done, the examples given render the UX unusable. it's nearly impossible to view all the photos in a set because the one being hovered covers the others. of course there are better ways to handle this in a finished product, but i thought you might be interested.
I appreciate your comment and think you're absolutely right. The experiment actually tries to make use of some cool animation effects while keeping a strict grid, so I'm happy you liked that part.
I am working on making the UX better by adding an interaction that uncovers the hidden blocks as the mouse approaches the edges of the full-size block. I'll update as it progresses. Thanks!
