There is a related discussion here: "Chuck Norris"-ing code. Something I wrote in response applies to your situation, I think-

Being paid to do nothing, or even being paid to do a bad job in spite of offering good work instead, is not good for one's psychology.

You've got some good advice already. I'd spend the extra time resume building, writing articles, learning new kits, trying to fix open bugs in things you use, and looking for new work. Don't feel pressured to leave but work on it at least passively. Do feel pressured to stay busy. It will help with your spirits. Having a long time to find a new job is a luxury and you may end up with something you love again. You have the time now to build skills and work samples to help you be ready if a dream job does appear.
