Two thoughts:
1. I wonder if it whistles?
2. It's about my skill level too.....I thank God I never tried!

Nah - I'm still here (I hope Otis is, too). Nothing surprises me these days - well, not much
Hopefully I don't sound like a know-it-all, but mainly this person's crime was simply not taking long enough in the planning stages. Wow, the "pattern" is all over the place, isn't it?
Henry's right: soda cans. Challenged aesthetics aside, that's an accident waiting to happen. Oh, well.
I had to laugh at his reasoning in his reply in the Question & Answer space:
"drilling is for weight reduction. priority to a cyclist. beauty is a priority to a collector. all this bicycle engineering is designed for a bike to be riddened. this Colnago was never designed to be a wall hanger. You ride hard! you ride fast! That is what this Colnago is about! Get that workout! Break that SWEAT! "
Gonna break something, I guess

If someone did steal his bike, both thief and victim would get what they deserved. Love the Marathon Man references in connection to a guy who sells reproduction Nazi Uniforms. At least he didn't drill the frame .

Szell: Is it safe?
Babe: Yes, it's safe, it's very safe, it's so safe you wouldn't believe it.
Szell: Is it safe?
Babe: No. It's not safe, it's... very dangerous, be careful.
One of my all-time favorite movies.

There was a guy I raced against that had a set of Sugino cranks with similar amounts of metal removed, it took a year, but at the start of one race when the gun went off and all were out of the saddle to get going... SNAP. DNF for him. After that all the drillium stuff came off his bike.

I got the drillium bug yesterday and did my outer NR ring, NR derailleur cages and even my son's chainring on his micro mini race bike. Thankfully nothing heartbreaking as the work he did. Less is more in my book...less of a chance to make it look like that thing. lol.
All done with the trusty Tru Drillium CF-13X 5spd "makes drillium dreams come true" drill press.

This is done on the holes of high performance disk rotors too - albeit for reasons of preventing high heat build up on the tip of the angle. The only picture I could quickly find is from a disk brake page:

My 'proper' drillium...Mattolini Corsa

Drilling a hole straight through flat metal leaves a right angle on the hole edge (when viewed in cross section). The tiniest fault on the tip of the angle can start a crack. Holes in high stress places should be radiused (sometimes called chamfering) as a curved surface is a great deal stronger.
Maybe just "breaking" the edge where the two angles meet, lightly, with a mounted, abrasive-impregnated silicone tip, or Cratex bit.
I wonder how many "drillium" guys do this? I tend to like the clean, sharp edges where the counter sinks and flats on my one chain ring meet, but I see your point about relieving that sharp edge.

That looks pretty good Henry. At least you got the holes laid out well and properly spaced, unlike the mess that is the subject of this thread. I've been tempted to do some more myself. Been 35 years since I drilled out my one set of chain rings. But I've been wondering if I can do something unusual and original. You know...something besides just holes.
Looking good Henry.

I just based the holes off of each tooth. John Thompson showed me and told me it's a easy way to do it and keeps spacing equal. The cages are a little tricky with the narrow curved contour and makes spacing a little trickier for me. This is the second NR derailleur I've done and it's turned out alright. It's more of a five footer. lol.
