The PuTTY iconography uses a stylized computer terminal displaying a kawaii face, representing the software's friendly nature despite its powerful functionality. The different icons distinguish PuTTY's various tools through color and added imagery. For instance, PSCP (secure copy) features a document with a downward arrow, while PSFTP (secure file transfer protocol) shows a pair of opposing arrows, symbolizing bi-directional transfer. The colors roughly correspond to the traffic light system, with green for connection tools (PuTTY, Plink), amber for file transfer tools (PSCP, PSFTP), and red for key generation (PuTTYgen). The overall design prioritizes simplicity and memorability over strict adherence to real-world terminal appearances or symbolic representation.
Simon Tatham, the author of PuTTY, provides a comprehensive explanation of the design choices behind the suite's various application icons. He begins by acknowledging the common confusion surrounding the seemingly arbitrary assignment of icons to specific tools. He then details the deliberate thought process that went into crafting each icon, emphasizing a systematic approach rooted in visual symbolism and the desire for clear differentiation.
The core concept revolves around representing each tool's function through metaphorical imagery related to its purpose. For example, PuTTY itself, being a terminal emulator, is symbolized by a computer terminal window, albeit an abstract and simplified one to accommodate the small icon size. This window motif is then modified and augmented to represent the related but distinct functions of the other tools. PuTTYgen, used for key generation, adds a golden key to the basic window icon, signifying its role in creating cryptographic keys. Pageant, the key agent, features a tiara superimposed on the window, symbolizing its function as a "king" or manager of keys. PSCP, the secure copy tool, incorporates a document with a prominent downward-pointing arrow, visually depicting the action of copying files to a destination. PSFTP, the secure file transfer tool, uses a similar document icon but with upward and downward arrows, representing bidirectional file transfer. PLink, the command-line connection tool, displays a lightning bolt over the window, symbolizing its fast and direct connection capability.
Tatham further elaborates on the practical considerations that influenced the icon design. He highlights the constraints imposed by limited resolution and the need for icons to be readily distinguishable, even at small sizes. This led to the adoption of simple, bold shapes and contrasting colors. He specifically addresses the choice of a yellow or gold color for elements representing security and encryption, aiming for a clear visual cue associated with these crucial functions. He also explains the deliberate use of distinct, easily identifiable shapes for each icon to prevent confusion among users.
Finally, Tatham acknowledges the subjective nature of aesthetics and the potential for differing interpretations of the iconography. While acknowledging that the chosen symbolism might not be universally intuitive, he defends the internal consistency and logical basis of the design decisions, emphasizing the importance of having a clear and reasoned rationale behind the visual representation of the PuTTY tool suite.

The Hacker News post "Iconography of the PuTTY tools" discussing Simon Tatham's blog post about the design of PuTTY's icons generated a moderate number of comments, mostly focusing on appreciation for Tatham's work and the quirky nature of the icons.
Several commenters express admiration for Simon Tatham's technical skills and the impact of his software, with PuTTY being frequently mentioned as a vital tool. The whimsical, almost amateurish quality of the icons is a recurring theme, with some appreciating the charm and others finding them mildly irritating. The discussion touches upon the difficulty of creating distinct icons for closely related tools, acknowledging Tatham's attempt to provide visual differentiation.
One commenter highlights the "hand-drawn" aesthetic of the icons, contrasting them with more polished, professional iconography. This sparks a brief side discussion about the evolution of computer graphics, with another user reminiscing about the early days of computing and the prevalence of simpler, less refined visuals. The limitations and constraints of earlier operating systems and display technologies are mentioned as a possible influence on the icon design.
Another thread emerges around the functionality of PuTTY itself. Commenters share their experiences and preferences regarding SSH clients, with some expressing ongoing loyalty to PuTTY despite the availability of alternatives. The discussion briefly touches on the evolution of SSH clients and the enduring relevance of PuTTY.
A few comments delve into the specific design choices of individual icons, attempting to decipher the logic behind them. The "network cable draped over a computer" interpretation of the PSCP icon is mentioned, as is the confusion surrounding the Pageant icon. The conversation underscores the challenge of creating intuitive and easily recognizable icons, especially for abstract concepts like network protocols or security tools.
Overall, the comments reflect a mixture of nostalgia, technical appreciation, and mild amusement towards the idiosyncratic iconography of the PuTTY suite. The discussion demonstrates the lasting impact of Tatham's work and the continued relevance of PuTTY in the world of system administration and network engineering. There's a subtle undercurrent of respect for the software's functionality overshadowing any critique of its somewhat unconventional visual presentation.
