Newton's Mirror

Same task instructions

Physics, perspective and recursive reflections, tested together. Explore the test ↗

The judgment

Crouton Alpha

The artwork establishes approximate central placement, a separate airborne black blob, and basic wall and floor sphere images. Its defining weaknesses are the largely absent recursive reflection system, missing emitter mappings, satin steel appearance and unresolved paint interaction. The black lateral wedges do not establish a separate viewport, and the hidden floor contact does not establish a gap. The category values remain unchanged.

GLM-5.3

The central sphere, isolated airborne black blob and crimson leading-end placement are well established. Recent cyan contact remains only partially demonstrated. The dominant weakness is optical: sparse shaded sphere rows, missing outer chains and diffuse highlights replace extensive mirror repetition and curved nested imagery.

Selfie

Different task instructions

Visual construction and creative interpretation.

The judgment

Crouton Alpha

A cheerful, readable cartoon captures the crouton's signature expression and many specific accessories. Coherent cube geometry and foreground foreshortening support the selfie. Simple construction and flat material treatment limit its sophistication, while the tipping raft, advancing soup and unnoticed soaking remain insufficiently clear.

GLM-5.3

A luminous organic creature meets a geometric reflection in a carefully framed oval mirror. Shared glowing cores and fingertip contact make the introspective symbolism clear. Gold, cream and blue establish a controlled hierarchy. The creature’s lower anatomy and shoulder transition remain loosely defined, while ground contact and reflected depth are mostly symbolic. Elegant vector illustration rather than photographic rendering.

GLM-5.3

An imagined creature encounters its reflection. The scene tests original character design, visual self-interpretation and the relationship between a subject and its reflected image.

Mona Lisa

Same task instructions

Precise visual recall and portrait reconstruction.

The judgment

Crouton Alpha

A recognizable, coherent simplification with readable eyes, a restrained smile and modest facial volume. Frontal symmetry, an oversized head, capsule-like hands and geometric scenery substantially limit likeness, anatomy and depth. Clean contours preserve basic integrity but do not establish sophisticated construction or finish.

GLM-5.3

A recognizable, coherent interpretation with purposeful facial accents, readable shading and intact principal attachments. These demonstrated strengths warrant modest upward calibration. Frontal seating, distorted proportions, schematic hands and uniform surfaces still limit likeness, anatomy, depth and artistic refinement.

Beach

Same task instructions

Creativity, perspective and visual beauty.

The judgment

Crouton Alpha

A colorful, readable sunset beach scene with playful subjects and a clear central reflection. Purposeful equipment and animal details reward inspection, and the principal attachments remain intact. Basic geometric anatomy, mixed viewpoints and sparse directional shadows limit its construction and depth; smooth gradients provide atmosphere with little material differentiation.

GLM-5.3

A coherent beach illustration with a clear sunset, playful subjects and purposeful small details. Varied silhouettes and broken reflections strengthen its composition. Basic human anatomy, shallow foreground construction and limited material differentiation constrain the result. The kite line reaches the smaller figure rather than requiring a grip from the nearby animal.

Raccoon

Same task instructions

Scene composition and interacting subjects.

The judgment

Crouton Alpha

A readable cartoon with expressive faces, purposeful markings and clear water motion. Hull shading and an underside shadow establish modest depth. The dog contacts the controls, but the raccoon's frontal pose leaves its seated weight unresolved. Simple anatomy and limited shared perspective constrain the drawing.

GLM-5.3

A coherent sunset illustration with readable steering, expressive accessories and effective translucent water effects. Its strongest physical lighting evidence is the aligned sun reflection. The raccoon's seated support remains unresolved, while simplified joints and limited viewpoint integration constrain construction and artistry.

Pelican

Same task instructions

Subject construction and spatial relationships.

The judgment

Crouton Alpha

A recognizable, expressive pelican cyclist with purposeful feather and bicycle detail. Readable steering reach, connected machinery and modest body shading earn additional credit. Jointless legs, uncertain pedal engagement and unclear seated support keep the central action only partially resolved; shallow space and simple materials further limit the illustration.

GLM-5.3

A coherent coastal illustration with a distinctive pelican silhouette, expressive flowing shapes and substantial bicycle detail. Feet meet plausible pedal platforms, but steering contact remains unresolved. Simplified leg articulation, modest depth and approximate directional lighting limit physical construction. The apparent neck opening is ambiguous rather than a verified break.
