Files are saved in your schematic folder, if it exists. Else, it will be saved in the current directory. If the program closes w/o output, then you need bigger radius (there is a message for that but it closes too fast).
Example input:
number of beams: 96
min radius: 13
max radius: 23
number of colors: 3
input colors in HEX (without #)
nr. 1: FF0000
nr. 2: 00FF00
nr. 3: 0000FF
processing...
Output:
