LibraryBox Bootcamp at VALA14 – suggest cool content

At VALA I will be working with Tom Edwards to present a bootcamp session on the LibraryBox.
We will be asking attendees to explore the content on our LibraryBox with their wireless-enabled devices. We are looking for cool, creative, delightful content that we can freely distribute.
It would be wonderful if you can post links to content that fits the bill. What have you found online that is in the public domain, or CC licensed or that you have created and are happy to give us permission to share. Anything we can put on a USB and that can be used by most smartphones, laptops and tablets!
Please leave us a comment with a link.
