No, because I couldn't afford to meet my family's basic monthly expenses after that much of a pay cut. If the pay cut and insurance were not an issue, I'd do it in a heartbeat.
For a while in 2000 I went to six hours a day, paid purely hourly, for some audio driver and desktop application development, for a company that made audio interfaces. It was great, actually. I'd show up fully energized to work, put in a _focused_ six hours, get a lot done, and leave. I was single and didn't need to earn that much to meet my needs. It was not sustainable long-term because of the lack of health insurance, but everything else about it was great.
