@chanduu Glad to notice your memory serves you well ;-) Memory is a great toolbox! You saw PinkDots before as gif image? Well... here it isn't. Aah. Flash. A game pops up and it's pointing in your direction: quess what PinkDots is. Express your quess in a scenario on Greenfoot :-) Creators create, have fun!

Very cool, my eyes started to hurt before all the dots went away, but it was very interesting in how a repeating pattern can trick our eyes into seeeing another thing.
