Flags and Waves
1986 film directed by William Reeves

Flags and Waves is a 13-second American short computer animation test clip which was created by animator Bill Reeves and Alain Fournier for Pixar sometime in 1986. The clip included waves reflecting a sunset and lapping against the shore. Reeves and Fournier made the project with the feedback of John Lasseter to work out details of rendering water and waves realistically, including lighting, motion, and shading.
It was first exhibited at SIGGRAPH in Dallas in August 1986, along with Lasseter's landmark computer-animated short Luxo Jr. and another test project Beach Chair, by Eben Ostby. The methods developed during the creation of this project were the basis of the water in Finding Nemo. It is based on an oceanographic model of ocean waves which Fournier dug out of the literature from the nineteenth century.
Flags and Waves can also be found as an easter egg in the Pixar Short Films Collection – Volume 1 which was released in November 2007.
Content
The thirteen-second short begins with the title Flags and Waves and under it the title in French, Drapeaux et Vagues, superimposed on the SMPTE color bars while a high-pitch frequency sound is made. The bars are revealed to be a flag that is flapping in the wind, as the noise shifts to the sound of a calm beachside.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Flags and Waves”, the useful work is to connect “1986 film directed by William Reeves” to the records capable of establishing context and consequence.
Attribution, date and provenance are strongest when supported by the original work, a catalogue record and documented transmission. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q54958519. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1986 and 2007.
Later fame can flatten the distinction between original context, subsequent adaptation and institutional collecting history. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
