没有，抱歉。我一直想重画一个。看起来还行的最大图标，是 20x20 那个，GNOME 的托盘图标用的就是它。再大，就难看了。16x16 和 20x20 的，都经过相当多手工调整，才让像素落位正确。如果只是把大图缩小，"BC" 的线条没有正好落在像素上的地方，像素就会模糊、别扭。
No, sorry. I've been meaning to redo it. The largest icon that still looks good is the 20x20 one which is used for the tray icon in GNOME. Any larger than that looks bad. The 16x16 and 20x20 ones have quite a bit of hand tweaking to get the pixels to work out right. If you just scale down a larger image, the pixels end up blurred and awkward in places where the lines in "BC" don't land square on a pixel.
带 alpha 通道的最好的 16x16 在 src/rc/bitcoin.ico。32x32 那版我不喜欢。
The best 16x16 with full alpha channel is in src/rc/bitcoin.ico. I don't like the 32x32 version.
我附上了 bitcoin20x20.png，即全透明 20x20 版本。
I'm attaching bitcoin20x20.png, the 20x20 version with full transparency.
