This is pretty amazing, like &#x27;davnicwil said. Personally though, the coolest thing about this is how easy it is to make if you have some way to make the mask.<p>It uses a Raspberry Pi Camera Module[1], which is $30, with no modifications other than removing the lens and adding the mask.<p>I wonder if you could make a mask by machining plastic down <i>very</i> thin, and then punching tiny holes through with the smallest endmill you could find.<p>[1]: <a href="https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;products&#x2F;camera-module&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.raspberrypi.org&#x2F;products&#x2F;camera-module&#x2F;</a>
