Back in the day, I ended up buying both MagicWB and MUI at the same time for a friend of mine. I had it registered in my name, since I did buy it. Didn't even have an Amiga to run it on. So my friend used it for a while, but now he no longer has an Amiga, and I do (funny how that turned out) and lo and behold, I still had it burned to a backup CD of mine, so I still have my licensed version of MUI and MagicWB.
Sadly, I still don't really use MagicWB, since the A4000D had OS3.9 on it.
But at one point in time I had been looking pretty long and hard at finding a MagicWB iconset for Gnome. I always loved the icons, and the fact that they used 8 colors was amazing.
