It may require some research, but you should still be able to find a download for the free Halls of Fame Origami edition. Like their many other limited editions, you can't load your own IR's, but the Origami samples cover a lot of ground. Perhaps the most striking feature is the pitch shift for the IR. I ended up realizing my gigabytes libraries of reverb impulses were overkill and I could do about anything convolution needed with what was already supplied in Origami.
Use to be and maybe still is included in the Yellow Tools suite, and with the full version you can load external IR's.
