OnLive's game streaming / insanity portal may be long, but through its partnership with AT&T, the company has just extended its free first year offer through Labor Day (September 6). Additionally, getting in by Labor Day will lock in the optional second year at $4.95/month.
If that wasn't enough, the service just added puzzle-platformer Trine to its growing list of titles available for streaming (it was previously available only as a demo). If you haven't already, sign-ups are still ongoing over at OnLive's official site -- and yes, you can still wear white while doing so. For now.
