A while ago I bought a first generation Lytro camera because I thought the concept is awesome, and to try it out I brought it with me on my visit to PHP South Coast 2015! To be honest I was a bit disappointed with the results, but since so many people there were interested in the little device, I decided to share the results anyway.
We've all been in this position; a group of people are talking about something and you happen to be at the same table as well. You haven't got a clue what everyone is talking about, but you don't want to appear stupid and so you just decide to be quiet and blur out something like "yeah it's great I use it a lot as well" every once in a while. Afterwards, you quickly Google for the thing they were talking about, because apparently you missed something?
