Santas gadget has a glitch, we have to check the video in HV19-SantaRider.zip...
There are 8 LEDs blinking in a cyclic way (=> 8 Bits?)
The color cycling does not work properly. The LED lights during the glitch are showing a code:
01001000

Converting this binary string using JavaScript:
String.fromCharCode(parseInt("01001000", 2))+
String.fromCharCode(parseInt("01010110", 2))+
String.fromCharCode(parseInt("00110001", 2))+
String.fromCharCode(parseInt("00111001", 2))+
String.fromCharCode(parseInt("01111011", 2))+
String.fromCharCode(parseInt("00110001", 2))+
String.fromCharCode(parseInt("01101101", 2))+
String.fromCharCode(parseInt("01011111", 2))+
String.fromCharCode(parseInt("01100001", 2))+
String.fromCharCode(parseInt("01101100", 2))+
String.fromCharCode(parseInt("01110011", 2))+
String.fromCharCode(parseInt("00110000", 2))+
String.fromCharCode(parseInt("01011111", 2))+
String.fromCharCode(parseInt("01110111", 2))+
String.fromCharCode(parseInt("00110000", 2))+
String.fromCharCode(parseInt("01110010", 2))+
String.fromCharCode(parseInt("01101011", 2))+
String.fromCharCode(parseInt("00110001", 2))+
String.fromCharCode(parseInt("01101110", 2))+
String.fromCharCode(parseInt("01100111", 2))+
String.fromCharCode(parseInt("01011111", 2))+
String.fromCharCode(parseInt("00110000", 2))+
String.fromCharCode(parseInt("01101110", 2))+
String.fromCharCode(parseInt("01011111", 2))+
String.fromCharCode(parseInt("01100001", 2))+
