Probably my wheelchair. It’s a pretty nifty little chair that has quite a few unique features. Also I would need it to get there anyway. Otherwise maybe one of my drawings.

my laptop so i can show off gnome and emacs (and my trackball!)

Beer. Not to show, just to enjoy it.

Probably, my grandfather’s blades as they tell pretty incredible stories. In order of when he was received them:

• USMC Kabar knife. He was issued the knife when he joined in WW2. He was lucky to avoid combat. Really, really lucky. He was on a troop transport en route to Kyushu when the surrender was signed on the USS Missouri and Operation Downfall was cancelled.

He went on to join the rubber industry, working for a major manufacturer in Indonesia. He kept his Kabar with him and used it a lot but never in violence. The combat knife became a tool of agriculture. The original leather rotted away in the tropical heat and humidity, was replaced with an improvised aluminum one. He was an avid gardener in his retirement and continued to use it somewhat like a hori-hori. The aluminum handle is falling off at this point, so, I’m going to eventually replace it with one made from olive wood to complete the “swords to plowshares” symbolism physically.

• Indonesian Parang. This blade is similar to a machete in design, about 20-24in (~51-61cm). My grandfather was given this blade at the rubber plantation by a deeply despondent man. The man had been pressured into taking part in an honor killing but didn’t have a violent bone in his body. Not knowing what to do and not wanting to murder another human being, he came to my grandfather who was well-respected in the community (he was ceremonially adopted by the local tribe). They came up with a solution. If he didn’t have his parang, he couldn’t perform the killing. So, he left it in my grandfather’s hands, making him promise to never return it.

While that man is probably long gone, I keep that promise myself and strive to ensure that the blade is never used for violence. Perhaps I’ll see if I can figure out a good mount for it to permanently prevent its removal from the scabbard. Its continued existence, to me, provides tangible evidence that there’s always another way.

I would bring my modular synthesizers. I brought my eurorack set up to a synth meet up and it was the most popular station next to the theremin

Ma dick

Edit: Buncha prudes…

I can’t tell you how happy I am that some of the replies here are about electronic music machines.

I’ve found it very difficult to find anything like r/synthesizers and it’s fellow circlejerk in Lemmy. If I’ve missed the obvious, please let me know.

For my show and tell I would bring my little analogue synthesiser and my special echo foot pedal. They are very simple but have unusual attributes that are easily demonstrated.

Probably either a Ken Payne bronze called The Trail of Change or my Ibanez s521 guitar with the ocean fade paint job.

Inherited it from a family member who loved southwestern and native American culture and history they shared with me so it’s some sentiment along with an interesting statue.

Most of what I own is minimal and function over form but I just think it looks awesome and is fun

My custom designed, fully 3D printed analog keyboards (which use 3D printed switches and stabilizers)!

That’s my AHEK-95 (typing on it every day) which was reviewed by a semi-famous keyboard YouTuber 😁

I’d also show off my Low Poly Rose Twist Vase design:

I’d roll up in my classic car that I’m restoring.

I’d bring my best girl Laika, because she’s awesome and I don’t have any interesting junk.

I’d bring my Moog Theramini. Nothing like playing the air waves! It’s magic science!

An amethyst crystal I found in my (gravel) driveway a full 4 years after moving in. It’s a good 8 inches/20cm long, and shaped like a tear drop. It’s amazing and I love it.

Fired and unfired pistol, rifle and shotgun ammo. I think I could give an interesting talk on the differences and the history of various cartridges, no fine details, only a broad overview. To keep it fun, I’d sprinkle in lots of things most people probably don’t know.

For example, did you know an AR-15 round is actually kinda wimpy, especially compared to a typical hunting round? In some states, ARs are illegal to hunt with because the bullet is deemed too small to make a clean kill. It’s basically a hauling ass .22.

And .22s are a neat topic by themselves. There’s crazy variety out there, even tracers!

I’d bring an amateur radio. Fun device that gives you access to an alternate method of communication. They’re old fashioned, but amateur radio gets used here and there in emergencies. I think it’s more of a precautionary thing from a practical perspective, but it’s still cool.
