Many of my friends (and myself) are turning 100000 years old in 2019. That is a nice and round number! And of course, there are only 10 types of people regarding all this: the ones that understand how one can become 100000 years old and the ones who do not ;-) The clue behind this is that 100000 in binary numbers is the same than 32 in decimal numbers, which is a much more reasonable age. Still, to honour this sort of magic geek number, I came up with a prototype birthday card that uses LEDs to illustrate this idea. In a typical computer system, the LEDs representing zeros would be off whereas the one would be on. However, since off LEDs are boring, I just used different colors. See below the result! :)

The sixth bit is needed because five bits only allow you to count to 1+2+4+8+16 = 31
