We are conducting a long-term monitoring campaign of the optical and near-IR brightness of gamma-ray bright blazars using the SMARTS 1.3m telescope and ANDICAM instrument. We confirm the brightness increase of 0235+164 noted in ATel #1744. We find that since August 20, 2008 (JD 2454698.85) the source has brightened from B=18.2 to B=16.3; from R=16.3 to R=14.6 and from J=13.8 to J=12.3. We continue to monitor this and other gamma-ray bright blazars on a near-daily basis. Our results are publicly available, and can be found at http://www.astro.yale.edu/smarts/glast/ Note that parts of the site are still under construction.
