I'm based in Edinburgh, 38 wks pregnant, and DF was visiting so we went round the Camera Obscura and World of Illusion tourist attraction for something to do this afternoon. I'd totally forgotten they have a heat-sensitive camera for visitors to mess around in front of which makes the hottest parts of your body glow bright red on a white screen. I walked in front of it and suddenly my baby was on full display!!! Not a clear image like a scan of course but a very obvious moving red blob in my tummy. The other visitors waiting their turn were all squealing and going 'awww!'
So if you're pregnant and want a fun peek, find yourselves somewhere with a heat-sensitive camera. It was so sweet :-)
