The first thing I wanted to show was an app called pplkpr.

This is an app which, when used with their $99 wrist band, measures heart rate when speaking to people to determine how you feel when speaking to specific people and tells you whether to spend more time with them or cut them out of your life.

This is a prime example of how technology like this is getting to the point of the unnecessary and ridiculous. Heart rate monitoring in particular could have great potential applications but some developers seem to be a bit off track.

I don’t really have much else to say about that, so the second thing I showed was an organisation called e-Nable.

They use 3D printing to create free prosthetics for people, mainly children it seems, who can not afford them for whatever reason.

This is a really amazing use of 3D printing and the fact that it is an open source project and the families get the prosthetics free of charge instead of having to spend thousands on one through the healthcare makes this even better.
This is exactly what 3D printing should be doing for the world and it’s heartwarming and inspiring to see that a project like this does exist.
