Sometime ago I posted a topic on Silverlight.net about how to get an control to follow a Path. This resulted in many good suggestions, but not actually what I wanted.
Today I then saw this on my RSS reader: Animation Along a Path for Silverlight, which sounded exactly like what I was looking for. I just wanted to give you, readers, an headsup on this one. I haven't actually tried this out yet, but it looks very promissing.
