Using a smartphone camera, you can easily express what you see through kaleidoscopes.
You can also use your front camera to make your own face.
You can adjust the size of the visible screen so that you can make it look bigger or smaller.
There is a pause feature, so you can stop your favorite screen.
Then you can save it on your smartphone if you like it.
(However, the current save function will save only 1/4 of the visible screen, and we will improve it later.)
The main function was the help of the source provided by flashmath.
