Today, Google posted a summary and photos of two wearable computing developer events it held for its "Project Glass" in early February in New York and San Francisco. The events, called Glass Foundry, gave developers who signed nondisclosure agreements early access to the application programming interface for the Glass wearable computing device and an opportunity to spend two days developing applications for them.

The events gave Google engineers an opportunity to get direct feedback from developers on the API before the general release of Glass Explorer, which is itself a developer-only release of the Glass hardware. The developers, who were a small subset of those who signed up for Google's Glass Explorer Program at the Google I/O event last June, formed teams for a "hackathon," producing more than 80 applications for Glass at the two events.

According to the Google Plus post by the Glass team, "Eight hard-working teams won the grand prize: Google will pick up the cost of their Glass Explorer Edition." Google is selling Glass Explorer Edition to those who pre-registered at I/O for $1,500. Google plans to hold more Glass Foundry events as it continues to develop the platform. Google's Senior Developer Advocate Timothy Jordan will give a first public look at the Glass development environment at South By Southwest Interactive on March 11 in Austin.
