SIGGRAPH, the Special Interest Group on Computer Graphics and Interactive Techniques of the Association for Computing Machinery (ACM), is best known for its annual conference and its long-running visual identity. The organization’s logo is a geometric mark built from a pair of interlocking partial spheres.
Design and History
The basic ACM SIGGRAPH logo consists of two parts: a graphic element and a text element. The graphic element is a pair of interlocking partial spheres, which can be represented in either two or three dimensions. The space between the two pieces forms a stylized “S,” alluding to the “S” in SIGGRAPH.[1] The organization logo and the annual conference logo are registered trademarks of the Association for Computing Machinery.[1]
While some online sources attribute the mark’s creation to graphic designer Peter Seitz in 1984, this attribution is not confirmed by official ACM SIGGRAPH materials. Seitz, who died in 2023, was a graphic designer and the first design director at the Walker Art Center in Minneapolis, and he helped organize the Minnesota chapter of SIGGRAPH.[2] However, no official documentation has been found that verifies him as the designer of the current logo or establishes a 1984 creation date.
ACM SIGGRAPH describes its unified graphic identity as a way to strengthen the organization’s name and image through a distinctive mark applied consistently across events, publications, and activities.[3]
Meaning and Symbolism
The logo’s meaning is documented directly by the organization. The interlocking partial spheres create negative space that reads as a stylized “S,” referencing the organization’s name. The spheres themselves can be rendered in either two or three dimensions, a flexibility that reflects the organization’s focus on computer graphics and interactive techniques.[1]
Typography and Design
ACM SIGGRAPH’s branding guidelines specify that the logo combines its graphic element with a text element, but the organization does not publicly document a specific typeface for the wordmark in its official logo guidelines.[1] The partial spheres may be shown in two or three dimensions, giving the mark a modular quality that adapts across applications.[1]
