Nerval's Lobster writes: Google remains tight-lipped about its roadmap for Google Glass, and its population of early-adopter "Explorers" remains small. Nonetheless, a growing collection of engineers, designers, and artists are creating their own accessories and add-ons for Glass — some of them useful, others totally whimsical. For example, there's Brooklyn designer Todd Blatt, who's relying on a 3D printer to churn out Glass accessories such as tiny flower-pots and pencil holders (not so useful) as well as a plastic camera cover (useful, at least for anyone in the vicinity who likes their privacy). Small firms such as GPOP and Remotte are likewise exploring how to best skin, dangle, screw, and attach hardware to Glass that makes it operate in whole new ways. (The avenues for exploration have opened up with the second generation of Google Glass, which includes a small screw in the right arm that can double as a mounting point for new tech.) Google seems to have no choice but to let this growing ecosystem thrive, even if some of the modifications (such as camera covers) don't necessarily suit its interests. But will the company actually say something about it?
