After many tests by my dear friend Issabella, I feel (almost) comfortable in releasing this new filter.
It will appear under the menu "<Image>/Diego/CrazyFilters/" (unless you modify the menu definition at the bottom of the source code).
Many of the results could appear a bit crazy (and that justifies the name of the menu group).
The craziness is due to the fact that each G'MIC Artistic Filter is applied using the DIVIDE layer mode.
All the G'MIC Filters of the Artistic group are exploited (one at a time, obviously, the one selected by the user at launch).
No additional resources are required (i.e. no subsidiary filters, no patterns, etc.).
Here the source, zipped
