The previous challenge was a lovely one, I'm not sure whether my new one can live up to it, but anyway, here it is.
New Challenge: Draw one of your favourite Lemmings levels (from one of the original games), only using the filled polygon tool, in
10 seconds flat.
(With filled polygon tool I mean the one that allows you to draw a path of points connected by lines, and when you double-click, the path gets closed and the enclosed area is filled. If you're not using MSPaint, anything that achieves an equivalent effect is allowed as well of course, and manually filling the area if the program doesn't provide filled polygon don't count towards the 10 second limit.)
After these 10 seconds, you may add a red dot for each entrance, a green dot for each exit, and resize the image, but nothing beyond that.
Put the name of the level in spoiler tags, so I can take a guess at what level is depicted there, and then verify whether my guess is correct.
Note: If it's evident to me that the level you picked is not amongst your favourites, i.e. you just picked it because it's easy to draw, then you'll have pretty low chances of winning.
Example:
Lemmings' Ark (Genesis Mayhem 30)
