Two years after 'Art&Math, a concept, an exhibition' at the University of Brussels, the idea was renewed on a smaller footprint and for a shorter duration, and with a slight variation in the title and emphasis that brought in a few new works : 'Art&Math:écriture(s)'. The location within in the framework of the Uccle Libraries triggered the subtitle, suggesting the different 'coding' possibilities that the generic French word may contain, from both a math and art perspective. This short paper reports the cases considered with pictorial examples. The workshops were chosen among the original ones with no direct relationship with the new flavor.
