Don't worry. You don't have to be good at math for this.
For this week I want you to pixel a piece that solely consists of 0°, 45° and 90° lines which basically means that you can only pixel straight lines. Heaven for all you AA haters out there.
There is no overall theme given. You can go crazy and pixel whatever you want.
