Perfect for using as navigation for the 'News' section of your site, a blog a ____ of the day site. Actually, that's why I'm coding this - for use with my WTFPotD.com website. All colors are customizable, as is the title of the calendar (if you want to include one), square/rounded corners, etc. Each day can link to either a page on your website or an image, document, audio/video file etc. It even creates the folder structure for you. Here is a screenshot of an example calendar created using the app. I'll release a beta version soon & take suggestions for additional features you'd like to see included in the final version of the app at that time.
