Any semi-competent programmer can reproduce it within a day or two(the OP did it in a shorter span of time). That won't help, and you aren't entitled to what you think you are.
And the work is totally his. The design was too similar, but still, its his work. He didn't steal your css or images, and though you might feel rough about it, it doesn't make it theft as you are putting it again and again.

Great for people who want to blog on Svbtle. If I don't and I like the idea, I am going to implement it and use it. I am glad we don't live in a world where you or anyone else can stop me from doing it.
The hard part was coming up with the original concept and design - kudos to you for the great work. Reproducing it is easy, and I don't think you have any right to stop me from doing it.
As another commenter pointed out, we don't actually want a world where Apple says MS stole its windows.
