Sometimes you have a lot of plots. And you want to show them to people.
WebOOT is a vision and an experimental python application which allows looking inside ROOT files and objects (e.g, trees and histograms) from a web browser. The main idea is that a plot you want to make is generated on demand from a URL. WebOOT blurs the distinction between the ROOT file and the file system, allowing you to easily compose and compare plots from many different places. With a surprising use of wildcards, many plots can be realised from the effort invested in just one.
