Yes - i only found out about pixel art when looking at mtPaint documentation the other day.
I like it as the images are so small you don't really need to add detail - if you open one in mtpaint and zoom in you would see what it looks like in a bigger size - kind of like an older lady seen from a distance she looks kinda alright but up close not so good.
.. concur with battleshooter's opinion - tiny images can be the life and breath of any gui (about the 1st thing I do with any recent opera browser is to get a skin with *color* icons for less eyestrain/mistakes).
Keep up the good work and give those old ladies a hug
last time I did pixel graphics was in the early 80's when I made a machine language pac-man game for the commodore 64 sure I was 10 at the time but it worked, I managed to have the sprites as they call them back then work well. Actually back home in Canada at my parents house I still have the disks where I saved it, lol Also I have a few things that my dad laughed at me and wouldn't patent because I was a 10yr old, the biggest loss was a scanner, back in the Commodore 64 early years, we only had a light pen that never worked for text. So to type out some times 30 pages plus of text to make a basic game from a magazine we had nothing. One day I figured if we combined a light pen to capture text at a rate of 6 inches, because that was the rate of text at the time. We could stop typing millions of text.
But my dad laughed and 6yrs later the scanner was introduced.
So today I'm not bill gates and if I was I would be here anyways lending a hand
