Features:
|
||||||
|
<ul>
|
||||||
|
<li> adapts the number of snow flakes to the CPU frequency to avoid hogging it,
|
||||||
|
<li> random wind change,
|
||||||
|
<li> the fallen snow accumulates on the windows and bottom of the screen,
|
||||||
|
</ul>
|
||||||
|
<br>
|
||||||
|
<br>
|
||||||
|
Limitations:
|
||||||
|
<ul>
|
||||||
|
<li> lot of flicker,
|
||||||
|
<li> it needs to set the desktop view flags to B_DRAW_ON_CHILDREN, which might gives weird drawing with some replicants afterwards,
|
||||||
|
</ul>
