Funnily enough I've been revisiting my xy_lcd patches that you were so kind about quite some time ago.

I've rebuilt the pseudogravity patch using jitter objects and javascript.

The js includes some routines for hit detection per object, it needs to be updated to use pythagoras theorem to better detect hit inside a circle...

The attached file might help you get started

PS I guess you've seen 47jJitterListener.pat in the jitter tutorials.

have a look at i_ispace.js in the int.lib source, which does just this

Actually I did look at your source. You are using 

"jit.gl.render". I am familiar with doing hit detection using

jitter. I am using the jsui sketch object. I believe (as far as 

I know) jsui sketch does not support JitterListener events. 

Someone please correct me if I am wrong...
