I havn't submitted anything here for a while but over a lazy lunch at my desk I found myself browsing the recent additions and having just aquired some shiny vaseline-glass* marbles I thought they'd make an interesting reflection, in this instance one is placed against a mirror.

* Vaseline glass is a glossy yellow-green glass that glows under UV light due to its uranium dioxide content, and it thus also has a low radioactivity (just over background-level), it is no longer made in several countires (UK, but not USA) due to the health risk to those who worked with it...
