I would love to have an excuse to put that on mine. If the job is tech or imaging related, then they would already be aware of it. For the others, at least it might cause a laugh or confuse them long enough to look it up (which means you might get remembered and taught them something). Just have to own it and not pre-apologize for it, power move, and don’t even act like it is any different when speaking at an interview (just like any of the other stuff you have listed). That or just put “GNU Image Manipulation Program Project” and leave it at that since it sounds “professional”.
That being said, I hate how overly “professional” people try to make every little thing sound much more “impressive” than they are. But I respect that you care more than I do/would, so no hate for you likely being much more likely to land a job. lol
One personal anecdote about wild resume with regards to a video response to questions I listened to while my boss was having to watch to make first picks for real interview. There was a woman that said her name was “Lix Dicks” (I can’t remember how it was actually spelled). I was like “Wait wait wait, did the sound just glitch out??” and my boss also had the same look on her face. We replayed it a few times trying to see if it was our PC or maybe the video. But my boss went back to the text of her resume, and shit was real. The person ended up not making it due to availability listed in a different section (her other previous work and qualifications would have had her much better than most of the others). Best believe we were sad that it meant the in-person interview didn’t happen. We still remember her though. Perfect qualifications AND such a wild name was such a loss for us.
GIMP is much more memorable for good or bad. I got over the name like 5mins after I first learned about it years ago. WLBR is so bland outside of the spelling. At least Blender kind of sounds like it blends elements to make something, and Plasma sounds like it would look nice. WLBR sounds frumpy/bland (though I would like to know what it will stand for), which is about as bad as trying too hard to sound “fresh/sexy” from a marketing standpoint. Maybe they could have gone with GRIP (GNU Raster Image Program) if the actual concern was about “offending” people while still being easy to remember? Idk, I suck at naming things.
