Kaleidoscope is a tool for creating artwork in the form of paintings. Its purpose is to give pleasure to the user by allowing him to look at a variety of visual effects that can be achieved through the use of various optical systems and palettes. It has been designed in such a way that the user can create his own art pieces, regardless of their subject matter.
The main element of the tool is the ability to choose from a variety of optical systems and palettes, which allows the user to create a unique painting. The tool contains a collection of various optical systems that can be used for the creation of a painting. Each of these systems has its own characteristics and properties. The user can select a system and then choose a palette, which is a collection of colors. Once the user has selected a palette, he can choose the type of the painting (e.g. landscape, portrait, or illustration).
