Are there any "guided" walkthroughs for someone who has never used Oberon (or any of its later versions like Bluebottle or A2) that demonstrate its most unique UI/UX aspects? Something along the lines of Russ Cox' Tour of the Acme Editor[0] but for Oberon? Oberon seems fascinating and I would like to eventually play around with it in an emulator, but any resources that show how it's being used (as opposed to a description of its design like in Wirth's book for example) would be appreciated.
