Lime Squares

I needed to contribute something to our company picnic this afternoon, and when I found that I had a bit of free time yesterday evening, I decided to do something new (in several senses) rather than just pull a unit of dessert out of the freezer. I'd noticed that a local grocery store has limes on special this week, so decided to work from there. ragnhildr has posted about her lime squares, so I thought I'd try something similar. This is what I came up with -- I'd be interested in comparing mine with hers. (The recipe is not yet linked from my main recipes page, pending possible tweaking of the recipe.)
