The Idea:
Every lurepet (big picture) that you see on the site has some "genes" and is drawn according to them.
After the best lurepets are selected they can be bred to make children looking like their parents. This is going to be repeated to create more and more beautiful lurepets.
And of course the reason to vote is to save the future humanity that is attacked by evil robots which has the only flaw - insane obsession with lurepets :)
Implementation:
The drawing logic which is 99% of all the logic, is written in Clojure. I'm very glad that I chose it, because I can not imagine beeing so productive in developing and maintaining (!) complex domain logic in a more verbose language like Java.
The web part currently is a set of static files: html, js and images. Cloudflare is used to CDN the static except the index.html. I hope that will help if there is a massive spike in traffic. The votes are processed from nginx logs in offline mode.
The development took about a year. Hope you will like the lurepet drawings and help to select the best genes.
