The blog theme is the great Acute theme, with some minor modifications.
In many of my demos I use background patterns from subtlepatterns. All of the great patterns are licensed under Attribution 3.0 Unported (CC BY 3.0) license.
Most of the images that appears on demos are created by bulgarian photographer Ivaylo Yovchev or by myself. Some of the images may not be included in the download files.
Google Fonts provides some great free, easy to use, ready for web fonts. We use them on the demos.
