Good design begins with a concept.
A well thought out, well designed concept is then followed through in every aspect of the design and in every medium.
Take the concept of a beehive (I did).
What do you think of when you think of a beehive? I think of a place where industrious bees gather to work hard and make honey. That's the idea. That's the concept.
As a developer, I work hard to produce something awesome, just like bees. Scroll though this site to see the results of that work.
