'Mars-DSP' 

People who have the EKO demo 'RU Xperienced' may find this  little 
program uncannily familiar??  Very simply, click to run, any other 
key than space to enter the main part,  cursor keys to move around 
the  landscape,  and  space  to return to that  dull  old  mundane 
reality known as the desktop.. Clear??

  CiH..
