Bob, Your last video is the best so far, but you still don't need to expand the arrays up before adding them. Just keep the arrays the same, and just slide/overlap them. You also don't need the plus sign to reappear. Just leave the plus alone, (you should still see it in the transparency or above the merge if you drop the two arrays) and slide the two arrays together.
No need for explosions either. A simple color transition after the sum has completed could indicate the new sum. This should be easier to develop since there would be no explosions, no array expanding, etc. and I think the subtlety is less confusing. . .Skip Cave . . . bob therriault wrote: > Hey Ric, > > I simplified the 'Sliding Matrix' version of Plus (+) a little.
