<p>Cyber features only straight lines and sharp angles for a futuristic, high-tech aesthetic. The Line variant maintains geometric clarity.</p>

<p>Cyber is one of our most challenging icon sets: no curves, only straight lines and sharp angles. Inspired by sci-fi aesthetics, it’s perfect for bold brands and futuristic tech.</p>

### **one sentence positioning**

The most mechanically extreme icon family available — zero curves, straight lines only, dark navy default, built for futuristic and high-tech interfaces.

---

### **what it signals**

Advanced technology, precision engineering, system control, architectural rigour, futuristic thinking.

---

### **best fit when**

- the interface must feel engineered and unmistakably high-tech with no compromise
- visual distinctiveness from standard rounded icon sets is a strategic requirement
- the product identity is built on AI, cybersecurity, infrastructure, robotics, or sci-fi UI

---

### **avoid when**

- the product needs any warmth, softness, or mainstream legibility
- a neutral UI language that adapts across audiences is the goal
- organic, human, or playful tone is needed

---

### **core visual rules**

- geometry: faceted, angular, polygonal — circles are approximated with straight segments; no true arcs exist anywhere
- terminals: sharp — all paths terminate at a hard angle, never softened
- corner language: sharp, faceted, straight-line-only construction throughout
- curves: none — the defining rule is zero Bézier curves in any icon
- detail density: low to medium
- silhouette: high visual energy — the absence of curves creates constant angular tension
- emotional tension: high — the sharp transitions produce more visual energy than any other family in this review

---

### **variants and hierarchy**

Cyber Line (1px, dark navy)

- Primary navigation and UI controls in high-tech products; the schematic-drawing aesthetic at its most direct

Cyber Duotone (1px, three-layer)

- Dark navy stroke + light blue tint fill + white base; feature sections and documentation with colour differentiation

**line/solid pairing rule** Cyber does not have a conventional solid sub-style. The Duotone three-layer construction serves the colour hierarchy role. Use Line for standard contexts and Duotone where category colour differentiation is needed.

---

### **small-size behavior**

- recommended minimum size: 16px
- best range: 16–48px
- notes: The straight-line joins create sharp termination points that can read as broken pixels on non-retina screens below 16px — the angular geometry requires sufficient physical pixel resolution to render cleanly.

---

### **motion behavior**

- strengths: crisp rotation perfectly suited to angular geometry, stable scaling, mechanical-feeling stroke animations
- ideal motion contexts: loading states in technical dashboards, system feedback loops, control panel interactions, data transition animations, hover states in developer tooling

---

### **typography pairing**

Geometric / futuristic sans (maximum cohesion)

- Space Grotesk, Eurostile, Bank Gothic, Aeonik, Barlow Condensed, Orbitron (display only)

Neutral UI sans (safe balance)

- IBM Plex Sans, Neue Haas Grotesk, Source Sans 3, Helvetica Now

Mono / terminal (control-surface feel)

- IBM Plex Mono, JetBrains Mono, Geist Mono, Space Mono, Source Code Pro

**type alignment rule** Prefer typefaces with geometric discipline, technical clarity, low softness, and strong stroke consistency. The type should look like it was built with a ruler — fonts where the 'a', 'e', and 'g' have visible calligraphic influence are wrong for Cyber.

**typefaces to avoid** Nunito, Poppins, Inter, Lato — humanist warmth directly contradicts the cold mechanical precision. Rounded terminal fonts of any weight create a personality mismatch with the straight-line construction.

---

### **mixing guidance**

Recommended with

- Sharp — both carry geometric technical authority; separate by specificity (Cyber for extreme tech, Sharp for enterprise general)

Possible with normalization

- Nova — both work for technical products; isolate Cyber to the most distinctive surfaces
- Core — technically compatible; keep Cyber for hero and identity moments, Core for utility controls

Avoid mixing with

- Freehand — the most extreme possible contrast in this library
- Plump — zero visual compatibility
- Flex — organic curves directly negate the zero-curve construction rule

**normalization rules when mixing**

- keep Cyber consistent within primary navigation and hero UI surfaces
- never mix Cyber with a rounded family in the same component or row
- if mixing with a neutral family (Core, Nova), isolate by surface — Cyber for the product's strongest brand moments, neutral family for utility

---

### **primary use cases**

- AI and machine learning product interfaces
- developer platforms and infrastructure tooling
- cybersecurity dashboards and security operations products
- crypto and Web3 interfaces
- data infrastructure and robotics software UIs
- sci-fi and gaming UI contexts

---

### **secondary use cases**

- high-tech marketing websites and futuristic brand systems
- control panels and monitoring tools
- advanced analytics and experimental design systems
