I recently took over some design work for an online configurator that allows people to personally design their glasses (or well... the framing for them). As you never really get a second chance to make a first impression, we looked at the home/landing page of the configurator which would consolidate all the incoming traffic. Within a couple of hours we came up with a simple yet effective design that is worth sharing for its structure and its components.
It only take a glance for this site to work. Through the photo it creates a mood with the characteristics of the product. It briefly explains the concept of the configurator and with the 3 doodles makes it main points. Further more this site introduces a colour theme with an explicit action color (in this case, orange is used throughout the app, to lead users).
With a very small amount of effort, this page welcomes, directs and convinces.
