This is extremely cool! Check out Google Browser Size.
Essentially, this web tool will draw an overlay map of your website marking the different resolution boundaries and showing you how likely people at different resolutions are to be able to see different parts of your website. Some people with low resolutions won’t scroll down to view the site. Here’s a quote from that page showing why this is important:
Using this visualization, Bruno confirmed that about 10% of users couldn’t see the download button without scrolling, and thus never noticed it. 10% may not sound like a lot, but in this context it turns out to mean a significant number of people weren’t downloading Google Earth. Using this data, the team was able to redesign the page to good effect.
This would be a great tool for artists to check the usability of their website at different resolutions and to get ideas on how to tweak the design for better results. What if potential employers simply don’t see all of your art or scroll to view all the content? Google Browser Size could be a great tool for analyzing that. Go check it out!
