Interior trim part of a motor vehicle

An interior trim part of a motor vehicle, comprising:

• a support, wherein the support is a substrate of the interior trim part and has a front side and a rear side opposite the front side and is at least partially opaque,
• a decorative cover applied to the front side of the substrate, wherein the decorative cover has a front side which provides an outermost surface of the interior trim part and has one or more layers,
• an illumination unit, which emits light, applied to the rear side of the substrate,
• wherein the substrate supports the decorative cover and the illumination unit, and includes a plurality of through-holes,
• wherein the one or more layers of the decorative cover overlie each through-hole of the plurality of through-holes of the substrate and extend across both the front surface of the substrate and the plurality of through-holes of the substrate such that a same number of the one or more layers of the decorative cover extend across both the front surface of the substrate and the plurality of through-holes of the substrate,
• wherein the decorative cover which overlies each through-hole of the plurality of through-holes has a uniformly closed surface and the through-holes are hidden until the illumination unit is activated,
• wherein, when activated, the illumination unit is arranged to emit light into different combinations of through-hole arrangements of the plurality of through-holes, sequentially, with each of the different combinations of through-hole arrangements providing different illuminated structures, respectively, on the front side of the decorative cover overlying the lighted plurality of through-holes,
• wherein, when activated, the illumination unit is arranged to emit light at a first time into a first combination of through-hole arrangements of the plurality of through-holes, and to emit light at a second time into a second combination of through-hole arrangements of the plurality of through-holes, with each of the first and second combinations of through-holes arrangements providing a first and second different illuminated structure, respectively, on the front side of the decorative cover overlying the lighted plurality of through-holes, and
• wherein the first and second different illuminated structures are of an illumination sequence to generate moving illumination.
