When I run the program in Wine, I see this image:

(mirror)
Is that just a default image of Windows or your programming environment, or a custom logo you've created?
If the latter, do you have a larger version of it?
If it doesn't have its own logo yet, maybe we could have some sort of logo design contest?
Everyone who'd feel like it could design something and you could pick a logo you like.
Or maybe the logo could be a selection of a group of tiles from the SNES graphics.
For apoplexy and the favicon? of popot.org I simply used the Prince's head (of the DOS version).
Just some ideas, maybe everything is good right now and a custom logo is unnecessary.
The reason I was thinking about this is that maybe the SNES editor could/should have its own board in the "Level Editors" section.
Which in itself is also just an idea that may or may not be worth investigating.
