Look! IKEA slat wall inspiration

Horizontal lines are a great way to visually "extend" your space and make it feel larger. We spotted this simple but striking wall treatment in one of the model showrooms at IKEA. They painted the wall a warm grey and put up evenly spaced dark stained 1 x 2's on the entire wall. We love the end result. What do you guys think? Is this something you'd consider for your place? Has anyone does this before? (a few more pics after the jump)
