I loved MS Paint. I thought I was going to be an online artist using it. But then I quickly found out its limitations (and my own). The spray can only let you have one color. I wanted 3 or more all mixed together for better blending. So that is the focus of my code kata today.
I picked out three colors in the same spectrum that blended well. Then every time I click and hole it starts adding dots in random points around my mouse. The slower I drag my mouse the denser the dots like a spray can.
Try out making up your own code kata, this one or send me your ideas. I'll try them out as well!
Aaaaaannnnnd some source code. I made the paint dots 4 pixels wide and my spray brush 32 coverage 32 pixels. Copy and paste this into your own python file.
# Have a paintbrush you can control with your mouse that sprays like the old
# MS Paint spray paint brush. But instead of one color, use three different
# colors all at once. That way there is no dominant color. This will help
# blend colors together.
