Interesting to note that in a convenience sample of ~10 UIST'25 papers, 100% have teaser images. The "visual abstract" seems to have reached complete coverage, despite not being a formal requirement of the CfP.
I reeeeally wanted to produce a mosaic of all the teaser images, but unfortunately the ACM DL's "download all proceedings" button is completely broken (like 500 Internal Server Error), and the site is too scrape-resilient to access programmatically. We've truly given up on having *a* proceedings in favor of random access.
