(CBS News) -- Google co-founder Sergey Brin was spotted wearing a pair of Google Glasses at a charity event in San Francisco Thursday night.

Brin was shown wearing the glasses by tech evangelist Robert Scoble, who sent out an Instagram picture of photographer Thomas Hawk's camera screen to his Twitter followers.
"The Google Glasses are real! Here is a set on @sergeybrinn cofounder of Googl @ Palace Hotel, San Francisco,"[sic] @Scobleizer tweeted.
Apparently, Brin wasn't ready for anyone else to try the prototype spectacles, but Scoble claimed that he could see the glasses working.
"Sergey wouldn't let me wear the Google Glasses but I could see they were flashing info to him. I so want one of these!" @Scobleizer tweeted.
A product of the Google's Project Glass, the glasses can display information and respond to voice commands. Some examples of how the glasses were most useful included: displaying the weather, reporting subway service outages and checking messages.
Since its announcement, the prototype augmented-reality glasses, for better or worse, have caused a stir. Critics have ranged between hilarious to brutal.
Thursday night, comedian Jimmy Kimmel spoofed the glasses on his show, "Jimmy Kimmel Live," showing a man injuring himself while taking a call.
"I want those Google Glasses so badly, but I also want to date women. Choices," tweeted @Digeratii, a Los Angeles-based movie director.
Technology blogger John Gruber was not easily impressed by Google's new project.
"Google's transition into the new Microsoft is now complete: fancy-pants sci-fi concept video to promote stunningly awkward augmented reality glasses," Gruber posted on his blog.
Project Glass is a part of Google X, an experimental arm of the search engine giant. The glasses are currently in testing phase. There's no confirmation on when the glasses might be available for purchase.
