I tried to write a mandlebrot plotter in FXYT. There are a number of challenges! First FXYT only provides a bounded loop - this can be overcome with a bit of inefficiency. However the deepest stack manipulation allowed is 3 values - the R command (Rotate the three values at the top of the data stack) which makes things supremely awkward. It could do with an PICK instruction (duplicate the n-th on the stack). However as an old FORTH programmer you always knew were getting into trouble if you used PICK. Despite these limitations I did figure out how to write a mandlebrot plotter. Alas it runs into an iterations limit if the depth is > 7, so here is a very low-res mandlebrot made with FXYT!
