the circles will probably ruin it, by making the text stick out over the boundaries of the circles, or be too small. Decide on what you're doing early on, and stick with it. Position your materials sympathetically to avoid motion-sickness . There's no point in using Prezi if you're just going to stick a load of paragraphs of text on the canvas at random, then plot a path between them. You may as well use PowerPoint as you're not exploiting the platform at all, and it'll probably leave the viewer slightly queasy.If you arrange your materials sympathetically, it's better for everyone. So try and move progressively and consistently between items -- from A to B to C, in a horizontal row or vertically or even in a circle, rather than from A -- Y -- D all over the place, wildly oscillating around the canvas. It's nice that Prezi will tilt to read everything as though it's horizontal -- it's fun to have a diagonal line of text and then a horizontal one, so that it zooms excitingly between them. But try and limit the number of these you have in a presentation -- changes of direction should be a neat special effect to punctuate your presentation, not the norm.There is a reason people get motion-sick on trains / trams far less than they do in cars, and it's to do with consistency of motion and the effect this has on the inner ear. Gradually accelerating train = fine, even
