Yesterday I was on a flight and tried to do a very quick prototype. Being on a plane I was inspired to do something based on free falling. I was sitting in the emergency exit.
I could record a video with a camera at the beginning and the end, and captured my screen during the whole process.

Unfortunately the battery run out very quickly and I had to rush into stopping and saving the project and the video just in time for the laptop to abruptly go off.
The experiment only lasted 28 minutes according to the screen capture video and I estimate it took a bit more than 10 minutes to prepare it before starting to record. Unity, the screen capture software, the webcam and the screen brightness drained the battery quickly.

I couldn't do much with the prototype itself. Almost no interaction was coded and at the end it is just a buch of boxes falling with a camera attached. I could have done more but the start was slow and even I was focused I lost a lot of time with things less important. There has been other times that I have donde prototypes very quickly but I now realize that I think and visualize a lot how I am going to implement it in a quick, dirty and simple way. Now that some time has passed I have thought some other ways I could approach the problem while in that moment I was wandering around doing the less important things. I also think the ability to find improvised solutions on the fly (pun intended!) can be trained and improved.
I still have the video material and the unity project. So I will find another moment to finish, or close, the project to a point where I can consider the experiment concluded and edit a nice video to publish.
