I wonder if anyone can direct me to a (free) software programme that will show a random coin toss.  It's for an icebreaker called Heads & Tails that involves tossing a coin but as I need to run it in front of 250 people I thought something projected onto a screen would be easier than trying to do it myself.  So far I've only been able to find software that's suitable for mobile phone.

Thanks,

Wrighty
