This is a minimalist calendar website with a clean and modern looking design. The prototype will work similar to google calendar in that there is a large UI with the month view by default, tabs to move between month, week, day. You can create an event, add people to the event via email and schedule it on your calendar. The application will also let you create your own lists. These lists will be a title, image (optional) and a URL (optional) and will show up on their own page in a pinterest-looking UI much like you could create a board or navigate through items in your board and add them to your calendar. Authentication should be available for email and Facebook.
The chrome extension will be a mechanism to pull an image onto the list as you're browsing the web. Front-end experience is very important here and experience with calendars on j-query or other libraries is a plus.
