If you don’t already check by the LOLcats website then I advise you to do so very regularly – it updates every few hours and provides smiles and sometimes laughs on a daily basis.
One fan of the site decided to take things a bit further, reproducing the classic ‘invisible bike’ LOLcat as a mural on the side of his building in San Francisco. If you fancy going an seeing it for real it’s on a tiny street called Quincy, between Grant and Kearny.
