hello
i have a code that is from instrucables:

the code is for build an analog led clock with arduino and rtc and shift register. the clock has three simple indicators(second, minutes, hour). but i would like change the indicators hands with special graphic shapes. like below images:
I think I need to change the array values but I can't
can any one help me for have three various indicators?
