Hola!
Being relatively new, I'm enjoying building out my skill set in both object manip and scripting in SL. And my thanks for all the ideas and discussion in these forums that have served as a springboard for my creativity and well as solving issues for me.
One particular idea I had, in experiencing translocation functions (moving from floor to floor for example), was developing an escalator style device that was essentially constantly (or apparently) in motion, which moved you up or down to the next floor. An extension of that would also be a Jetson's style tube or tube set that would simply elevate you up or down as a continuous function. I played a bit with llPUSH but want to refine this to approximate a true escalator and jet tube experience.
As always your feedback is most welcome!
