One day during summer we got an e-mail from outlying city Bangalore from one woman called Shubha Ravi. She wrote this e-mail, becuase her son Mihir likes Peter very much. She asked us to help her with an explanation how to program with Peter. She could not know, that this e-mail would start "International Peter's programming school".

This web page shows very shortly, what we together created with assistence of e-mails and ICQ. Nice memories have lasted. All created programs are picawares and interested people can download them for study, inspiration and entertainment.
