10. A Backup Heart

A short ish update - the foam model heart I got from Amazon has arrived! It's really pretty good, though I didn't expect the joining parts to be curved rather than flat. It's also quite pricey at £15. I was hoping that I might be able to use this heart as a back up in case my silicone one falls through. If the joining parts were flat I might have tried to stick it on a board and try to make a mould with it as well, but since it isn't I'm not sure how to make the mould. Either way, glad to have something that's actually very accurate just in case. 

The size is much more accurate than the heart I made

The seaaam. From the side I think it's slightly flatter than it should be

What it looks like opened up.

Due to a fire alarm at the Art and Design building, I also managed to talk to Ian, who reassured me that even if I can't make the heart controller part from scratch, the change to a pre-made one is still well within my proposal idea and allowed.
