While pottering about on the net I came across a flash based escape adventure called Morningstar. I'm posting hre since it has a space based theme and VO players may find it fun . Collect stuff, put it together, use it etc. There are plenty about but in terms of sound, graphics and animation this one is a wee gem, and will occupy a few hours while you puzzle it out .
