Anyone know of a Tick Data Simulator in any program format ?

[Robert Bianchi <r.bianchi@xxxxxxxxx>]

Hi TSers,
I am trying to find a free or low cost program that generates lots of 
simulated tick data time series. It does not worry me what format it is 
written in (e.g. XL, C, C++, Matlab, SAS, S-Plus, etc) and it is not 
important what the simulation process is. I just require something that 
pumps outs lots of tick data which I can access for collection.
Best Regards,
