Prompt

Apply a Block Glitch effect by displacing selected rectangular image patches horizontally and vertically. Create hard-edged seams, duplicated fragments, mismatched local textures, and occasional narrow pixel strips. Leave enough surrounding areas intact to make the fragmented image clearly recognizable; keep the original subject and composition.

Paste it into LetzAI with your own image to apply the effect ↗

Identify

Rectangular parts of the image are shifting.

Principle

Data blocks1 are copied as examples and repositioned.

Try it out

Set different block sizes.

Classification

Schematic visualization2, not neural inference.

04 AI illustration: A news broadcast image shows rectangular fragments of the face shifted hoA news broadcast image shows rectangular fragments of the face shifted horizontally. This illustrates Block Glitch by displacing discrete data segments of different sizes across the frame.Illustration generated for the Atlas (AI)

05 AI illustration: A hallway scene features several rectangular sections of the floor and waA hallway scene features several rectangular sections of the floor and walls copied and moved. These shifted blocks demonstrate the effect by breaking the visual continuity of the space.Illustration generated for the Atlas (AI)
