Hi Niico, well the idea came when I read this blog post (http://www.gabrielweinberg.com/blog/2011/02/if-i-were-starti...)

I told myself that it would be a good idea to take the concept to another level. Even though I'm not a good coder (I'm more a tech guy), it was a concept easy enough for me to get started.

It took me about 3-4 days part time.
