This suddenly triggered a memory of one specific art attack but I've been scouring YouTube and so far haven't had much luck finding it. I haven't seen all that's available but I'm getting a bit sick of it despite my desire to still see it again. Maybe someone here remembers it.

• I would have watched it in the 90s I think sometimes between 94-96. But I can't say for sure it wasn't a rerun from an earlier period
• The particular art attack was a night scene of traffic on what I think was a wet road with a truck or lorry, the perspective is of the lorry heading towards the viewer, though a little bit profile, not directly head on
• I think it was drawn on black paper
• It may have been done with white and yellow chalk, certainly I remember the colours white and yellow being used
• It was demonstrating ideas around being able to hint at the impression of objects at night without drawing the full object, only the outline of parts of it that would be illuminated by light sources which were headlights and smaller lights attached to the sides and corners of the lorry
• It involved doing something kind of like how a little kid would draw a sun with a crude circle and rays but then some quite clever technique was employed to smudge those little suns and their rays in very straight lines used to trace the hint of outlines of traffic
• It was finally finished off with some kind reflection on the road surface, don't recall how he did it

I've going through ep after ep, nowhere to be found. The wiki for art attack has only two mentions of "night" and it's neither of the two mentioned episodes, there's only one mention of "traffic" and it's in regards to using traffic cones. There's a mention of "truck" but that wasn't it either, I checked. There's no mention of "lorry". Couldn't find anything to do with "wet roads" either. Driving me nuts.
