介绍：简约而不简单....颜色可随意调制，最好用Blend工具。
效果图如下：话说这个图会不会太大了点 ０＿０
外观简单，制作也十分简单：Microsoft.Expression.Interactions.dll和System.Windows.Interactivity.dll是必不可少的！

里面凌乱的名字，请忽略吧，都是Blend自动生成的，也难得改了，将就将就吧。基本上没有什么技术难点，就是翻转一下角度，然后鼠标移上，按下，移开各自关联一个简单的动画。
使用方法：
1 <Button Tag="待办事项" Height="200" Width="200" Style="{DynamicResource MetroButtonStyle}"> 2 <Button.Background> 3 <LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"> 4 <GradientStop Color="#d04f8f" Offset="1"/> 5 <GradientStop Color="#c84f89"/> 6 </LinearGradientBrush> 7 </Button.Background> 8 </Button>
颜色和大小请随意。中间图形可以用其他内容代替！
