This one took me quite a while to do, mainly because a thing here and there wasn't quite right and I kept tweaking left, right and centre to make sure I got it as good as I can get it.
This came about when I was experimenting with the Linux Mint logo and seeing if I could turn it into a 3D glass object. So I messed around with different ideas and techniques in GIMP until I got this.
I hope you like it. Please let me know what you think of it, for good or bad.
