Escher Blocks

Escher Blocks — An isometric sketchbook.
Escher Blocks is a drawing app for creating block-based 3D art and isometric line drawings. Stack colorful cubes to form shapes, then trace their edges to explore structure and depth. Start with blocks, move to lines, or draw directly in 3D—it’s entirely up to you.
Use imagination and creativity to build impossible objects and optical illusions & forms that loop, twist, and gently challenge how depth and perspective are perceived, all within a clean isometric grid.
Whether you’re learning 3D perspective, practicing technical drawing, or doodling, Escher Blocks makes 3D drawing feel intuitive, expressive, and fun.

Key Features:
* Build 3D forms by stacking colored cubes
* Create impossible objects and paradoxical structures
* Convert blocks into clean isometric line drawings
* Draw edges and wireframes directly in 3D space
* Learn perspective by seeing blocks before drawing lines
* Lightweight, distraction-free drawing experience
* Designed for artists, students, and 3D enthusiasts
