Here's a quick way of looking at the numbers you generated from cube 5 (2 2$5)<;._3 <"1 (5 *4 3)$ paint
This organizes them in groups of 3 (for each pixel) and then in 5x5 groups (for each square). You can see by scrolling over horizontally that your bottom square has values outside the 0..255 range in your pixels, so that means you need to scale your calculation by something related to the right argument to cube. I think Mike Day's code might do that, and it also looks like he has gone into deeper analysis on your code. But perhaps being able to inspect your numbers can also help you understand your code?
