If you got laid off and are even remotely curious about startups, there are at least two meetings a day you can attend to brainstorm with fellow entrepreneurs.
Office space and access to computers are not the issue (it's nice because it's a way for people to meet in person, which is a great boost to the entrepreneur spirit). Connecting with the existing entrepreneurs and joining one of the many projects is the key.
