This is another one of those “How do you do that in Expression Design?” blogs. Consider the following goo:

It’s green, bubbly, disgusting and was drawn completely in Expression Design using a combination of different live effects. It’s really easy to draw when you know what effects to apply, so all you have to do is learn how to draw yourself a puddle of goo.

There are more than a few ways you can draw puddles of goop – one is to start out with the B-Spline tool on a new document with a stroke color and start drawing the outline of the goo. That can be a bit tedious.

Another way – you can drawn a bunch of differently-sized circles overlapping each other at various points on the artboard, select them all and use the ‘Unite’ path operation to combine them so that only the outline of all of the circles remain.

The way I like to draw puddles is to make use of the Polyline Tool  imageand draw a polygon with many jagged edges like this one:

Then switch to the Convert Anchor Point tool  image and start clicking on the anchor points to convert them from jagged to rounded edges.

Finish rounding all of the jagged anchor points and then give the shape a white fill. This is what you should end up with, or something similar in appearance.

Believe it or not, that’s the hard part. Now let’s add the effects. Under Effects on the right side, click the  imagebutton and under Surface choose “Craquelure”. On the settings for Craquelure, you want to set “Crack Spacing” to 21, “Crack Depth” to 10 and “Crack Brightness” to 9. Also, set the stroke color for the object to nothing. Your shape now has some texture to it. This should be what you end up with:

Okay, we’re going to add ANOTHER Craquelure effect, so again choose  imageand “Surface” and “Craquelure”. This time you want to set “Crack Spacing” to 7, “Crack Depth” to 10 and “Crack Brightness” to 8. This should be what you end up with:

The next effect we want to add is the “Plaster” effect, which is also under “Surface”. The plaster settings should be set as follows: “Image Balance” – 20; “Light Position” – Top; “Smoothness” – 2. Set the Foreground Color to #327C13, or R: 50, G: 124, B: 19 and the Background Color to #ABC41F or R: 171, G: 196, B: 31. Your shape should now be a blurry, bubbly greenish-yellow that looks something like this:

One more effect and we’ll be done! Add the “Plastic Wrap” effect. This can be found also under “Surface”. Change the settings to the following: “Highlight Strength” – 20; “Detail” – 10; “Smoothness” – 9; And this should be what you end up with:

You can adjust the length of each of the slime puddle “feet” with the Direct Selection tool. Add a couple of eyes. For a really cool effect, add a filled oval to the slime puddle and select both, then select Path, Back Minus Front. The slime puddle not only has a hole in it, but the edges are correctly adjusted with the “Plastic Wrap” effect to look rounded off. You can do this multiple times to make a makeshift face:

Have fun experimenting with different colors, shapes and effect combinations!
