Nope... not "modern art"! Here is an infrared image illustrating what misinstallation of fiberglass bat insulation can lead to... interstitial air bypasses. We didn't need a blower door for this one either... as there was a ventilation fan that pulled cold air in from the exterior vent without any problem. The ductwork for this vent was quite obviously not hooked up properly either... hence the wall that looks like "modern art" to the Ti32 thermal imager!
