Hence the name. This reminds me of my childhood. I remember playing with a toy similar to a small "telescope". When you look inside and move the toy, you can see the picture shifting endlessly. It really was a fun toy! I wonder if kids even have them these days...
The upper pics are actually something that I made with another mobile app, PicsArt Kaleidoscope. One finger + rather small space (approx. 6x9 cm) made the whole thing pretty challenging.
The topic of kaleidoscope also reminds me of good old Sumo Paint. Down here you see some of my old experimentations with Sumo. More old stuff here. I'm sure you can notice the progress. :D
