at the moment this patch takes a live camera feed, and uses the centre of mass to erase an image of reveal another.

But it does so in large square chunks. I know how to change the pen size but does anyone know how to soften the edges and even change the shape?

Here's the patch so far- excuse the mess.

jit-lcd-smooth-the-edges

You could try sending the output of the lcd to a jit.fastblur and play with

I once tried it but it wasn't giving me enough blurring and ended up having

to move to shader computations. Then the abstraction jit.slab.gauss.6x is

You could try sending the output of the lcd to a jit.fastblur and play with
the center and ring sizes

to move to shader computations.  Then the abstraction jit.slab.gauss.6x is
really nice.
