*Boring post alert*

At work I run simulations overnight. Sometimes they fall over and sometimes they finish early and provide a solution. These simulations are in Excel and in simulation software (Simul8).

I was wondering if there was a way for me to see the screen(s) from at home (I have two PC's at work running simulations). I do quite a bit of work in the evening and it'd be nice to know how the simulations are getting on. if they've finished/crashed etc. I guess all I need is some kind of screen sharing software running but it's hard to know which works without someone being at at the other end. Free and unobtrusive would be good too.

Any advice would be great!
