Gridlocked is a grid-based, post-format supporting, layout-shuffling, minimalistic theme for creatives designed by ThemeForest. Gridlocked is both a classic portfolio for showcasing your work and a modern tumblr-style blogging system.
A truly versatile theme, Gridlocked can be configured to focus on your work, your blogging, or both. Support for post formats means you can jazz up your blog with your own self-hosted video, audio, images, galleries, asides, links, quotes and of course good old standard posts.
