The Block Inject module allows for regions to be created and injected in the middle of chosen node types.
You can create any number of regions to inject as well as select as many node types you would like these regions to be injected in. The blocks you assign to these regions will then appear in the middle of the body field of these node types if the number of paragraphs is bigger than 2.
Bamboo is a responsive Drupal 7 theme designed and developed by Danny Englander (@Danny_Englander). Based on the CSS Skeleton Framework, it allows for a choice of backgrounds, color palettes, sidebars and fonts in the theme's settings page.
Bamboo is aimed at users who want to get a nice looking theme up and running fast, and may not want to take the time to create a sub-theme and fuss about with regions, settings, media queries, and other super technical things. It's also aimed at the casual Drupal user who has some familiarity with building sites. This is designed with this type of user in mind, so it may not be for the developer per se who would most likely use Omega or Zen. This theme also does not require any base theme. I am considering offering some downloadable Features as well, i.e. "Slideshow", "Gallery", etc...
