A commenter named Holger suggested that I list the mosaics in the sidebar so that they'd be easier to find. It's an excellent suggestion and I've started the process.
While I generally like Blogger, it does have limitations. The first is that there seems to be a limit as to how many posts will display with a given tag. For instance, if you click on the "101 Dalmatians" tag at the bottom of an entry, you will not get all the posts relating to that feature. For that reason, there are no sidebar links listed for Pinocchio or 101 Dalmatians yet as I have to figure out how I'm going to handle them.
The other thing is that Blogger will display the posts relating to a tag with the newest on top. As a result, the actual mosaic, which is usually the first thing I post relating to a cartoon, will be at the bottom with later commentary above it.
In the future, I'll probably put together a "Best of" list on the sidebar, with articles that I think still have value even though they may have been posted some time ago.
