Google Calendar’s visual design was updated recently.
The changes and reasons are explained here:
I want to just point out some interesting part of that, the part that is always the most interesting/relevant to my own self:
Why we made these changes
The way people use and experience the web is evolving, and our goal is to give you a more seamless and consistent online experience — one that works no matter which Google product you’re using or what device you’re using it on. The new Google experience that we’re working toward is founded on three key design principles:
Focus: With the design changes in the coming weeks and months, we’re bringing forward the stuff that matters to you and getting all the other clutter out of your way.
Elasticity: The new design will soon allow you to seamlessly transition from your desktop computer to your mobile phone to your tablet, while keeping a consistent visual experience. We aim to bring you this flexibility without sacrificing style or usefulness.
Effortlessness: Our design philosophy is to combine power with simplicity. We want to keep our look simple and clean. But behind the seemingly simple design, the changes use new technologies to make sure you have all the power of the web behind you.
