Introducing Cinch, a new Tumblr theme by Untitled Themes. Cinch is another interactive theme similar to Impress, just less reliant on modern technology. Cinch is in fact based on Kinley and features a lot of professional features and a great deal of options to customize.
You can preview the theme on the preview blog, however the panning navigation which makes this theme unique and quite interactive is disabled on it.
This theme will be a premium theme in the future but is free to all at the moment in its beta state. Feel free to install it, exercise it, critique it, customize it, make it yours.
