Here’s some free versions of Ong’s Hat for Kindle and as an ePub (for iPad, Nook, Sony Reader, Adobe Dimensions, et al). I’ll be putting these up on the newly redesigned incunabula.org (see design here) in 2012. Thought you might want to grab one now as my holiday present to you. Thanks to Matt for doing the great work to get these done. If you would like your Kindle edition (free or otherwise) of Ong’s Hat signed it is now on Kindlegraph.
If you’re looking for a free copy of the Incunabula: Ong’s Hat book, you may find several formats here or here. The Zip/ISO of the original CD ROM/eBook can now be downloaded here and the graphic novel here. The other content will be back soon or you may look for other free things on Archive.org like audio, etc.
