Leonel has been working with MS Excel, MS PowerPoint, MS Word, and all MS Office since its first version. One day he discovered that he could create nice tiling patterns using the copy and paste functions of a worksheet. Since then he has been experimenting with several combinations of texts, images, effects, colors, etc., to create visually attractive patterns to use in cards, web page backgrounds, diplomas, homeworks, etc., wherever a sprinkle of creativity can be dropped. He also likes MS PowerPoint's drawing features, so he explored how to use little known capabilities like free form dots edition. One day he discovered that that feature could be use to retrace bitmaps and convert them to vectorized graphics. Leonel also likes to buy on eBay, he has found that great items are for auction if you know how to hunt for them, it is not just a matter of search for a name but the better the search is refined the best offers that can be obtained.
Leonel has always been interested in the field of Human Computer Interaction, and has developed a method for designing interactive systems called Structured User Interface Design or SUID.
