For anybody who plays Stepmania here, I have made a simfile for the guided tour of the tanasinn chamber. I recommend 2x or 3x, as it is an xmod file.

As this simfile attempts to be the closest thing humanly possible to making steps for tanasinn, only VIPPERS with extreme levels of tanasinn will be able to pass this. I would suggest FailOff.
