Dear MathGroup members, making presentations on Mathematics or Physics, sometimes I need to discuss independently of one another certain parts of mathematical expressions belonging to the same formula. This requires to separate them out or somehow to highlight them. Such an aim may be achieved in several ways. Say, below a simple mathematical formula is defined. It consists of two parts. By a mouse click one of the parts is blended while the other changes its color to a more striking: part1 = Graphics[ Text[Style["AB+", "Times New Roman", Italic, 22, FontColor -> Dynamic[col1]]], ImageSize -> {80, 70}]; part2 = Graphics[ Text[Style["xy", "Times New Roman", Italic, 22, FontColor -> Dynamic[col2]]], ImageSize -> {80, 70}]; collst1 = {Black, Black}; collst2 = {Blue, Gray}; collst3 = {Gray, Blue}; DynamicModule[{col1 = Black, col2 = Black}, EventHandler[ GraphicsRow[{part1, part2}, Spacings -> -35], {"MouseClicked" :> ({col1, col2} = {col1, col2} /.{collst3 -> collst1, collst1 -> collst2, collst2 -> collst3})}]] Now comes my question: It would still better catch the eye, if (before the part in question will definitely change its color to Blue) it blinks few times. Say, it may change few times its color between blue and gray, or it may increase and decrease its size few times or so. Have you an idea of how to reach such a result?
