It is a crucial task to stimulate and to encourage students' interests on mathematical thinking as well as mathematical proving of certain mathematical facts by providing a visible environment, so that the students can catch related mathematical ideas with the help of their own visual intuition. the column of proofs without words (PWWs) has served this goal well over the past thirty years. indeed, PWWs are pictures or diagrams that help the students to see why a particular statement may be true, and also to see how one might begin to go about proving it true. based on this understanding, the notion of dynamic proofs without words is proposed in this paper, followed by some dynamically elegant visual demonstrations of certain mathematical ideas including AG inequality, sums of constant powers of consecutive integers, trigonometric identities including double-angle formulas. using GSPA and MathType as tools, the dynamic environments for PWWS are managed within powerpoint, some of those static configurations found in the column of proofs without words have been transformed into dynamic presentations. all dynamic environments in a CD-ROM are available on request.
