A fun app this time - MagiCirGen - a magic circle (or Mahoujin) generator.
I had the general idea for long time, but finally I made it as an app.
The first idea I wanted was that I just want my own auto-generated "Mahoujin". It is a kind of so called Magic Circle, western terminology, while "Mahoujin" is the Japanese terminology in a slightly different purpose. Anyway, creating the pattern by hand is fun but takes time, so I wanted to program to generate it.
Then, the second idea was "Rotation in 3D". This is inspired by Pokemon Go's Pokestop. The rotating ring was cool and I wanted to generate a similar pattern.
Finally, recently I saw an article regarding "Mahoujin" projecting toward ground using pocket-projector to take Magic Circle effect in a photo.
It was kind of exciting, and it finally made me actually code the App to do so.
