sorry fellow NoScript user, but this code relies on the computational power of YOUR hardware :-o

this means, it needs access to JAVASCRIPT to calculate all the geometry and dynamically display... all,
so, please turn JS on just for this page if you want to control it -

maybe one day i'll put on some sort of jpeg-gallery just for you :-)

overcautious? - check the code, it's all here

as each level increases the elaboration time,
at high levels it may freeze or crash the browser* -
to compare, on my PC** it takes...
lvl 1: 150ms (W 60) 39
lvl 2: 300ms (W 180) 64
lvl 3: 700ms (W 400) 130
lvl 4: 3.4" (W 1.3) 695
lvl 5: 25" (W 10) 5.4
lvl 6: 233" (W 80) 171.161
lvl 7: ? ?frozen @9485, "regrouping..."
lvl 8: ?
lvl 9: ?

* as it tries to use more RAM than available
