in gridflow you only need a handful of objects and it is faster than my gem-pix-to-sig-to-pix approach and python, though it is still quite slow. i can now run 320x240 * 20fps in realtime. but more important: with gridflow it's quite simple to do and very flexible.
I just thought of another way of doing slitscanning that runs much faster. You need to use a [#store] with "put_at" and write at a different row each time while reading back the image in whole rows. e.g. you send a (240,2)-sized grid to the left of the store. This avoids any clumsy copyings of the buffers. To make it work with columns, do it with rows but flip the image along the main diagonal using [#transpose].
I think that I'll try to do it in cellular_1d.pd soon, to replace the current junk.
