Absolutely terrific plugin here. I would be completely willing to pay for a pro version if you ever decide to offer extensive customization to this plugin. Congratulations on this!
I'm helping a client of mine with a new design for her blog using WP Tiles. She is a survivalist on the Discovery Channel: http://zerraexpeditions.com/zerra-news/. Is there any way you could provide some guidance on how to program the hover effect? When you hover over a tile, the tile changes color and a title appears (similar to: http://www.athousandguitars.com). I believe Maya from LA designed this site. I would greatly appreciate some direction on this and code snippets if it's a simple modification. Thanks so much!!!
