What if you could draw with a brush that used spiroids as paint!

Making geometric patterns on paper by pushing a pen through a hole in a disc and rotating it inside another disc can be a hours of fun. But it’s a bit old school.

What if the discs didn't have to be round? What if they could be square?
What if they could be heart shaped?

What if the pen could change colour as you draw?
What if the pen could even change size as you draw?

Oh...
What if you could make a paintbrush that used tiny versions of these spiroid patterns as it's paint!

You can!

Spiroids can be drawn inside circles, ellipses, rectangles, triangles and even inside heart shapes.
The pen can be a pencil just a single pixel wide, or it can be a brush 20 times wider.
And it can change colors and width as you draw.

In Gyroid mode you can paint with a brush that draws small spiroids as you paint.
They're beautiful.

And of course you can print them and save them to your photo album. Or share them with your friends.

Round discs with pen and paper is old school. Go new school with Spiroids and have even more fun.
