I often see superbly restored SGI equipment at VCF and also own a few SGI equipment that I hope to get to some point in my life but I have never seen any interesting new software or usage of these machines other than the stock "cool" demo programs(The file manager, the gears demo and others running at the same time). Is there any actual cool homebrew occuring on these platforms?

I'm not aware of any cool homebrew, but there is a certain level of cool being able to compile the code for some N64 games using the original IDO compiler on original hardware. You can even compile one of the many decompiled games like Super Mario 64, Banjo Kazooie and more that all will produce the exact binary shipped on the cartridge byte for byte, all from reverse engineered work to create byte matching equivalent C code.

  It runs like arse though. I'm working on some OpenGL stuff at least.

Yes! I don't use my O2 a lot (I think the PSU is flaky, and I'm not super interested in IRIX), but I'm aware of at least https://forums.sgi.sh/index.php https://forums.sgi.sh/index.php, among other similar sites, full of people porting/developing software for IRIX. It's a pretty active community for a 90s workstation platform, the most active one I'm aware of!

I think the lack of a real usable emulator for SGIs is holding back any kind of homebrew. I say this as one of the developer's that got SGI Indy emulation working in MAME. Yes, it works, but it's too slow and too old to be usable. I spent some time after the MAME effort working on a custom high performance emulator for Crimson/Onyx/Reality Engine, but I've kind of burned out again. Maybe some day if I'm really driven again, and had help. I've done most of the reverse engineering already, it's just a lot of code. I think that if a high performance, usable emulator for some of the big systems existed I think some of the old software might be rediscovered and show up on the internet.

  I think the problem was that the machines were always very expensive, even used. My Fuel has an SSD and Id use it daily except: - It's loud - It's single core - It's a furnace - It's very very loud It has a fairly modern Emacs, ssh and a non distracting UX. The browser is the only real thing that is too old to be useful, feature and performance wise, but that's just bonus points productivity wise (besides, rdesktop into a modern machine and you can watch youtube) If I had a 900 MHz O2 loaded with RAM, and an SSD (SCSI SSD, ha!) it'd probably be my daily driver.

    I have a 600MHz RM7k O2, and my 700MHz R16k Fuel blows it out of the water. The O2 isn't that quiet or that quick even with upgrades! What SSD are you running? I'm still on 10k SCSI drives selected for the quietness of their bearings.

      Right now I cant get to the machine (off, in the basement) but it is some run-of-the-mill SATA drives using a SATA expansion card. It works great but I just use it for /opt since I ran out time to move more of the machine into it. You cant boot off the SSD, so I still use a SCSI but you can replace that too if you boot the SGI off the network. Silent SGI: Having gotten rid of the SCSI drives completely w/ the network boot, you can put a modern, more silent, PSU [1] (but hurry, ones w/ enough current on 5V (?) are rare), and then replace the GPU and CPU fans and turn of environmental monitoring. [1] i had to replace mine; my 500 MHz Fuel is notorious for bad psu

        Do not turn off environmental monitoring. That's for debugging only. That's how people are cooking the video cards. Please get your fuel /properly/ repaired by say weblacky on irixnet. The reason why? With env monitoring off, the system won't respond to overheating on the graphics card and it'll cook it alive. The fuel has notoriously bad airflow (air doesn't move right angles)

The main watering hole for the hobbyist community around these machines vanished from the internet a while back, taking the forums and info around porting software with it.. I guess some of it is available via wayback etc.
