It still to this day has a thriving scene, lots of interesting quirky programs still being written for it. (https://oric.org/)
There is also a thriving hardware hacking scene of course, 21st century peripherals being brought to the user base, and so on.
One of the more interesting things (besides LOCI), is the orix system, which is a 'unix-like' environment for the Oric, which uses avariant of the 6502 cpu.
Its pretty cool - and fun if you're an Oric nerd - but if you like 'unix-like' systems for unusual platforms, put this one in your list to check out, as well:

Oh, yeah, I know 'unix-like' has a wide scale of sincerity, this is not quite there .. yet .. in terms of having all the unix bits, really .. but it is at least bootstrap in that kind of direction, for the Oric .. anyway ..
