A button, a tool-tip, and a widget. I've attached what would be my entries to this contest if I didn't suck at design, please feel free to use them as a guide for size and content.
add-to-queue-button - The button that shows next to a link or on top of a video when the user mouses over a video or a video link with this browser extension installed. Up to 100x30.
notice-box-for-mouse-over-button - A little tool-tip that appears upon mousing over a button, like the add to queue button. Will need to be flexible in size.
queue-container - Lower right corner of browser window, contains title text of "up next on zowify", a close button, a thumbnail of the next video that will play (thumbnail can be any size or aspect ratio within this window) and an expand button. Up to 150x100. I was hoping to keep the contest low budget, so just the collapsed version if possible please.
I'd like for the queue-container to be anchored to the chrome window, to appear as if attached to the window, but also appear as if above the web page. Above the page, attached to the lower right corner of the window. Let me know if you have any questions!
