白黒ステレオグラム

A simple white and black stereogram.
When you tap the display order,
It changes to "ID" and "random".
The stereogram of "ID" changes in a fixed order.
"Random" changes the stereogram randomly.
When you tap the appearance,
It changes to "A" and "B".
Because the appearance changes depending on the parallel method and the crossing method,
Both are supported.
When you tap the stereogram image,
It changes to another stereogram.
When you tap the "!!" image,
The contents of the image displayed in stereogram are displayed.
The app icon also has a little trick.
Thank you.
