The aim of this series of applications is to enhance students' spatial perception capacity by means of exercises that require the student to concentrate on mentally recreating the figures represented. Each application is designed with an increasing level of difficulty, designed to increase the students' concentration and train their spatial perception. In order to foment a degree of competition among the users and motivate them to try to improve the result achieved in each exercise, a scoring system was implemented, showing the best score obtained both by the user and in the class as a whole. Macromedia Flash tools were used to develop the applications, as these allow the generation of Web-viewable applications of a very small size. In this way, we were able to develop applications accessible to the students and that do not entail any very demanding minimum requirements.
