DELTA DRAWING Spinnaker Software 215 First St. Cambridge, MA 02142 (617) 868-4700 $49.95, 16K-cartridge Reviewed by John & Mary Harrison Delta Drawing is a turtle graphics language simple enough for our children to enjoy and rich enough for us to find challenging. Unlike other turtle graphics implementations, the Delta turtle responds to single letter commands: D for Draw, E for Erase, R for Right, L for Left, etc. And there is no penalty for pressing a nonfunctioning key. Merely by pushing a few keys, our three-year-old can actually make the computer do something. He likes that. Our seven-year-old has learned to plan her pictures and is becoming aware of how small ideas can lead to big results. These works of art (stick men can be beautiful) can then be saved on disk and called up for later display. It would be misleading to think of Delta Drawing as just a fancy doodling program in color. It is an excellent introduction to the whole concept of programming. Simpler than Logo, it appeals to children too young to spell as well as older children and adults. A maximum of four turtles can be displayed and moved simultaneously. This teaches symmetry while producing striking and sometimes unexpected results. Other features include the ability to enlarge, shrink, or reverse pictures using simple commands. Up to nine pictures can be developed and saved in a process that is transparent to the user. These procedures are named X1 to X9 automatically by Delta Drawing as they are saved. The user references one of Delta Drawing is an excellent introduction to the whole concept of programming. these procedures by calling its name as another Delta command. The Editor provides a text mode for the creation and editing of Delta programs without redrawing the entire picture. The packaging and documentation are excellent. All of Spinnaker's products are packaged in firm reusable plastic boxes which encourage proper care. The documentation consists of a small spiral-bound book and a quick reference card. Each of the commands is illustrated in step-by-step examples that fully describe the capabilities of Delta Drawing. Thus it is possible to be creating exciting visual displays while still learning how to use the program. Delta Drawing is a powerful education tool. It is not intended to replace BASIC or Logo, but can be used effectively to lay a firm foundation for the future study of these and other languages. Drawing pictures is fun. By the use of simple commands, Delta Drawing encourages organizational skills and procedural thinking even in the very young. It is well worth the purchase price.
