Below is a link which allow you to download some of his wonderful examples and Delphi creations.
Some of these were presented at the last four workshops. The zip file names are self explanatory!
Thanks a lot Heimo!
A big thank you to Mrs Dalize van Heerden of UNISA and Mrs Gerda van der Merwe of HS Hartbeespoort who have helped with all the arrangements. It was a wonderful day indeed!
