Usually, the design of merchandise that companies give away at all technical conferences is quite sad. Exceptions in my experience are only the rare Google hat that I took at Neurips in 2016 and the 'GPU poor' cap from fal. Very often, the merchandise looks childish or cringeworthy. There is such a lack of cool techie stuff that I even had to design and print a few t-shirts with AI jokes for myself. Recently, I came across merchandise from Cloud.ru in collaboration with designer Gleb Kostin (see pictures) - it looks quite cool and is dedicated to the launch of a new platform for working with GenAI. By the way, drop examples of cool merchandise that you like in the comments.
