Hi together, <br><br>I am new to this list. So perhaps I should introduce myself. I am 25 year old german student studying&nbsp; congitive neuroscience&nbsp; in Utrecht/Netherlands. I want to use squeak /etoys mainly for exploring and visualizing some ideas in a quick way. 
<br><br>Right now I want to build a prototype for an experiment and&nbsp; think that this is a good project to learn a bit more about squeak. <br><br>I want to program a sequence of objects appearing on different positions on the screen one after the other and later in a random order. 
<br>A very dirty way to do so is just script doing something like. <br>object1 show. <br>script wait for 1000ms. <br>object1 hide<br>object2 show<br>script wait for 1000ms. <br><br>I know that this is a very basic question but couldn't find the answer, as I don't know what it is I am looking for. 
<br><br>thanks a lot<br><br>martin<br>
