Google Glass is an interesting piece of wearable device with an infusive opportunities for mashup applications. Although, in some circles Google Glass is still viewed with reluctance and skepticism similar to the dwindling future of the 3D glasses of the time when the Avatar movie had come out in cinema. However, there is an immense amount of untapped uses that could be added on to Google Glass with the sheer creative delights of mashups reloaded. One of the best places to harness the abilities of such a device is to head over to a hackathon near you and try it out for yourself. There is always a hackathon going on some where or another. Best place to check is on Google or at a meetup.
