Sweet work. I wish someone would apply for my jobs with that as their referenced work.
It is strange; usually you see someone put their name in the footer, have an about page, or at least sign their work in a meta tag somewhere. I couldn't figure out who was behind it until I hit the "donate" link which reveals the donation will go to "yavorskiy.s@gmail.com", AKA Sergij Javors'kij of Khmel'nic'kij Ukraine, whose unfinished home page is at inetcat.com according to WHOIS. Why not see if Mr. Javors'kij is looking for work and offer him a job?
Cool site. You should add some tiles where the edges seamlessly repeat so there is no blank space between the end of one tile edge and the beginning of another.
This is great. Any plans for integrating an image upload to make my own pattern?
