hi everyone!

first of all i would like to introduce myself to the list: i work as artist and would describe myself as mathematica noob. being an artist i am mainly engaged in visualizing chaotic systems, such as iterated function systems or time series from experimental data. now, here comes the mathematica bit for which i hope to find some information on this list (at the moment i do not own mathematica but have the chance to use it on one of the machines at the local university (mathematica 6)).

i would be very happy to find some tips for those basic noob questions:

- how can i import a 3 column (x,y,z) file into mathematica an do a 3d plot? ps: i managed the 2d version with something like data=Import["file", List] and ListPlot ... or so ...

- is there an expression that colors certain values from the list with a color of my choice? (eg: the mean values from the list are rendered "red")

- and number three: how can i tell mathematica to do the following: take an irrational number such as PI. now create a list according to the following rule: 3.14159265 ....->
x,y,z
3,1,4
1,5,9
2,6,5
.,.,.

looking forward to your tips!
thank you for your time
