So here's another celebration; it's been 500 years ago that Joenen van Aken a.k.a. Jeroen Bosch a.k.a. Hieronymus Bosch, died (1516); therefore this is the "Bosch" year in Holland.
Here's a link in which you can wander around in one of his paintings:
Jheronimus Bosch - the Garden of Earthly Delights
and another one to discover some more:
Discover Hieronymus Bosch in ’s-Hertogenbosch (Den Bosch)
and you can find several (long) documentaries on the man at you tube.
So collage your own 'garden of delight' or 'ship of fools' or create creatures we've never seen before or anything else that triggers your fantasy...., be inspired by "Jheronimus".
