Oh yeah I've seen that. Awesome!
Their is also a company that will mix your ashes in with an agrocrete mold with your nameplate on it and place it along overharvested reefs to give new structure for growth. One last hooraah for something that gave us so much pleasure
I've seen these a couple times. Always impressive. Too bad more organizations don't do something like this. I did look into donating a while back, but couldn't find any info.
