Thanks Ric, The speed is definitely an issue in order to cover the key concepts in 15-20 seconds. Longer and you have tutorials that may not be referenced as readily, shorter and it quickly becomes overload.
I had a chance to watch a live Cirque de Soleil performance in December and realized that there is a form of performance in which you cannot possibly keep track of all that is going on, and yet it is still possible to enjoy it. The advantage of these animations is that you can view them repeatedly, with text accompaniment on the reference page to provide the learner some tools to structure the experience. Your favourite is now on the jwiki page for Plus (+) as 'Plus 2X2 3d'. It is a bit of a hybrid between 'Plus 3X3' and 'Plus 2X2' All may review the animations here: http://www.jsoftware.com/jwiki/Vocabulary/plus Cheers, bob On -Mar5-2010, at -Mar5-20103:43 PM, Sherlock, Ric wrote: > I like the way array addition is shown in plus 3x3, but I think that there > are perhaps too many numbers so that it looks a bit busy and hard to grasp at > that speed. > > But my favourite is plus2.key (not linked on the wiki page) > > http://www.youtube.com/watch?v=FBlNIAKDveU&feature=channel > >> From: bob therriault >> >> Hey everybody, >> >> I've posted three versions of the Plus (+) animation on the Jwiki here: >> http://www.jsoftware.com/jwiki/Vocabulary/plus >> These incorporate previous suggestions of including J code, colliding >> 3d matrix planes (with explosions!) and 2d rearrangements.
