Let $T$ be the Pascal-adic transformation. For any measurable function $g$, we consider the corrections to the ergodic theorem

\[
\sum_{k=0}^{j-1} g(T^k x) - \frac jL \sum_{k=0}^{L-1} g(T^k x).
\]
When seen as graphs of functions defined on $\{0,\ldots,L-1\}$, we show for a suitable class of functions $g$ that these quantities, once properly renormalized, converge to (part of) the graph of a self-affine function. The latter only depends on the ergodic component of $x$, and is a deformation of the so-called Blancmange function. We also briefly describe the links with a series of works on Conway recursive \$10,000 sequence.
