The lab has relied on PsychToolbox from the start and we have often reached out to the main developer, Mario Kleiner, for additional functionality and received exceptional support. PsychToolbox is certainly one of the most valuable services to the vision science community.
After years of discussions and uncertainty of how it could be made sustainable, it was now easier than ever to support the development & maintenance of PsychToolbox. If you run a lab & use PsychToolbox for your experiments, you should consider becoming a community member here: https://psychtoolbox.net.
Our lab just did.
