ORIGINAL USE-CASE DEMONSTRATIONS
Weekly Product Review (84 seconds) and Concept 01 - Desk Light (57 seconds).
Original VESPER scripts and graphics, created for this demo in 2026. Fictional participants, decisions, metrics and product; no real meeting, people, product offer or affiliation. English speech is synthetically generated using the installed Microsoft Zira system voice and does not imitate a named person.
Original demonstration scripts and graphics are distributed under CC0 1.0: https://creativecommons.org/publicdomain/zero/1.0/
Scripts: /source/demo-scripts.json. Generation source included in downloadable project.
No third-party recordings or personal information were used for these two demos.

VESPER original design assets (2026):
27 hand-drawn SVG control icons, the Vesper Display title/label alphabet (105 glyphs), lettermark, open-icon control layout and edge-cut frame language.
Apache License 2.0. Source drawings and font-generation scripts are in the source archive.
The Vesper Display family is an original display alphabet; DM Sans remains the separately licensed long-text face.
OpenType.js (MIT) and polygon-clipping (MIT) are build-time tools used to serialize/merge the original letter outlines; neither supplies the glyph drawings or is loaded by the player.


Liquid glass design reference: AI-generated mockup created with OpenAI ImageGen from the existing VESPER/Sintel screenshot, used as a design reference only. The playable panel is implemented in original CSS, not a bitmap. Sintel remains credited above. Generated reference: /design/liquid-glass-mockup.png.

Pulse data: compact waveform and RMS measurements derived from each demo soundtrack, with the same media attribution and licence as the corresponding recording above. The decoder timestamps are aligned before analysis; the original playable media is unchanged.

Timeline frame previews: one-second stills extracted from each corresponding demo recording and packed into JPEG storyboards, with WebVTT metadata. The same media attribution and licence as the recording apply; Sintel images are CC BY 3.0 derivatives, NASA stills retain the credit above, and the original meeting/product stills are CC0. Frames are resized and letterboxed without cropping.
