irise

Which prototyping software is best for interactive prototypes? Axure, iRise ... other?

I want to find a great interactive prototyping tool.

Note that I said "interactive."  Interactive wireframes are fine; but static wireframes are not.

Clean, production-ready code is not necessary. I don't need collaboration or documentation features.  Flow diagrams are only a plus.

Which tools should I spend the time to research?  iRise?  Axure?  Others?

iRise: Fast prototyping tool?

I want an opinion about iRise:

By watching their videos I got an impression that is too back-end
focussed. No much room for a 'rapid' UX mind-set. For that I tend to
stand for Axure. Light and fast prototypes with documentation. I have
no experience with iRise and depending on complexity it might bring
benefits to the requirements management and other parts of the
application development, e.g. back-end programming, test scripts and
so on. It looks overkilling to test UX, though.

Is someone, focused on UX, actually using it? For fast simulations in
an iterative design process?

Rapid Prototyping Tools

Hello,

I am looking for a tool that would essentially allow me to make a "paper
prototype" that I can share with a remote participant. I have been
using DENIM (http://dub.washington.edu/denim/)- which does everything I
need. I am looking for an alternative because of performance issues.
Any recommendations?
