Science addicts here?....
I'm one....especially archaeology, astronomy.
I stumbled upon this [url]http://www.nowykurier.com/toys/gravity/gravity.html[/url] on a guitar forum ([url]http://www.tdpri.com/forum/bad-dog-cafe/517529-appreciating-gravity-things.html[/url])
I don't fully understand how to use it yet but it looks interesting enough to putz with.
To keep up and feed my neurons I go here...[I]all[/I] science topics are available if remotely interested:

Carry on....
