Tidal Memories displays Dinacon photos against an animated intertidal zone.
Tidal Memories is an interactive, environmentally-informed visualization of photos posted to Matrix (Riot) during Dinacon. It displays photos taken during Dinacon, on a representation of the intertidal zone in front of the Dinacon site in Koh Lon, Phuket, in Thailand.
The live site is here.
Photos are positioned vertical along the intertidal zone, according to the tide level when they were taken (or, at least, posted to Riot).
They are positioned horizontally from midnight on the left, to the following midnight on the right.
Some memories are covered by the water. The tide level indicates the current tide in Koh Lon. At high tide, you won’t see much.
Mouse over a photo to see its details.
Here are photos at high and low tide, of the intertidal zone in front of the Dinacon site.
If you have your audio turned up, you may be able to hear waves. These were recorded on site.
During (part of) Dinacon, the display brightness was keyed to an on-site light sensor. During night (and when severely overcast), the image would fade to black; during twilight (and when slightly overcast) it would darken. The current display doesn’t attempt to simulate this, since doing so would render the display unusable during much of the Western hemisphere’s waking hours.
Matrix is an open network for decentralized communication. Riot is a set of clients (web, desktop, mobile) for viewing and posting to Matrix chat rooms. During Dinacon, participants posted images to Matrix (Riot), as well as to Twitter and Instagram.

Matrix-photo-gallery is a more conventional photo gallery for Matrix (Riot) rooms. I wrote it as a debugging tool, along the way to this more artistic rendition.
Matrix-archive uses similar code to grab photos and chatroom transcripts from Matrix. It was created for use by the documentation team.
