I'm not normally into "trinkets" for the cruiser but I've seen a lot of interest for a cup holder solution for our trucks on Mud. I'm on vacation at Winter Park, CO so I decided to browse Craigist for the surrounding area. I stumbled across some sweet cup holders that I figured would be popular for our community. I don't know if they've already been featured on Mud, but here's the link. No affiliation.
