The present invention is a tool for enhancing interest in and memory retention of visual alphanumeric text messages and images that are readable both as conventional two-dimensional printed text messages and as perceived three-dimensional text and images. This tool is a hand-held article that comprises a clear pocket capable of receiving inserted materials and displaying the inserted concept or information that a teacher wants to convey to the students. The student can continually view and recite the inserted information as part of the retention process for learning the material. Because of the shape and composition of the present invention, it can be used as a recreational device. The article can be passed between students as the students recite the information contained in the window pocket. The repetition of the chants serves to reinforce the retention of the chanted information.
