The Bethesda crab is changing color

Right in the center of Bethesda, at the corner of Wisconsin Avenue and East-West Highway is the Crescent Building.  When you are driving down Old Georgetown Road it is probably the most recognizable thing you see, mostly because of the odd neon sculpture at the top.  I actually first posted about it over  a decade ago, after I found out it is an abstract crab.  It has been a bright red companion for as long as I can remember.  Not too long ago, however, it turned blue for a short period of time (Maryland blue crab perhaps?) before going back to the traditional red.  Now it is at it again! Except, instead of just being blue, it is cycling through a whole palette of collors.  I stood by the road in the middle of the night just to bring you all the colors it can be.  At the bottom there is a video where you can watch the whole cycle.
