Continuing my recent megapixel fixation, check out this insane, 19200 x 2400 monitor [link via Airtight Interactive]. Aside from the obvious expense and physical demands of this kind of configuration, such a wide layout would impose some new UI challenges (e.g. look at the control elements spread all the way to the right and left). Of course, with higher DPI displays coming and resolution-independent UI support coming from Microsoft and Apple, there’s plenty of work ahead (if nothing else, so that your Photoshop toolbar doesn’t end up being 8mm wide on screen).
