This is to demonstrate the effect stacking (combining) ability. The bars are drawn up at the top, then reflected (the reflection is slightly darkened), then a red mirror is applied, and finally a 'clear' (no colour tint) mirror is applied. Oh yeah, and if you look closely you'll see the bars are in fact embossed.
Here's the embossed blocks idea. The blocks are 4 pixels by 4 pixels with a 2 pixel vertical and horizontal spacing. This gives you a sort of LED style look that other analyzers have. Also note that in Sexy v1.6 it was impossible to have the grid lines any colour other than black. Note that in this screenshot (and the one below) the background is solid.
Nothing here that can't be done in v1.6 except for the embossed effect. At high resolutions it's hard to notice the embossed effect so I may add a "heavy embossed" style that will be 2 pixels (instead of 1 as seen above).
The colours are kinda lame since I don't have any of the user interface done (so it's hard to make nice colours) but you may recognize the colouring style as being the "Fire" style.
