When my brother, CC Columbo, started his Second Life® one of his activities was building a parkland with a memorial for his daughter. At one point he owned most of the mainland region called Nangrim and when I came from the Teen Grid I added to it, helping to form a sprawling landscape where people could relax in a "natural" setting. Over time it had many forms but it always featured a focus point about my niece, usually pictures and an info signboard. Eventually we sold some land when CC minimized his time in-world and then sold the balance when a pre-gambling ban casino kept the sim full, completely locking us out.
Not too long ago I used nearly the last of my Christmas gift money to get a premium account for my regular Alt and then had her buy a 512m2 plot of land (SLurl) to use as a home and to re-create -- if only in part -- the Memorial Park. Since then I sometimes wander by the computer while CC is using it for something and spot the SL viewer, open and showing his avie sitting at the grave.
