Here's a link to a video that shows the type of foam from a whipped cream dispenser. The ISI website also has a bunch of foam recipes:

I can't find a video for the other type. However, on Bravo's website, if you look for Marcel's audition video, he makes a carrot foam using an immersion blender but it doesn't really show it that well. It's just a short glimpse at him doing it. Basically though, the liquid that you are going to foam needs to be strongly flavored and seasoned or else it won't have any taste. When you taste the liquid before you foam it, if you think it tastes just right then add more salt. If you think it's slightly salty, add more salt. Then, when you foam it up it will taste perfect.
Here's one that you can serve with grilled salmon or scallops:
1 cup water
6 Tbsp. Butter
1/2 cup prepared horseradish
2 Tbsp. Lemon Juice
1 tsp. Lecithin
Kosher Salt
In a two-quart sauce pan, combine the water, butter, and lemon and heat over moderate temp. until the butter is melted and the water is about 140 degrees. Remove from heat and stir in the horseradish and lecithin. Season well with salt and add more horseradish if needed. To foam, place the immersion blender in the sauce pan and tilt the sauce pan at a 20 (approx.) degree angle. Using the blender, "bounce" the sauce off the upward side of the pan (you'll need to practice to get the angle and technique right, but don't move the blender around. Once you get the proper angle you can keep the blender there and the sauce will foam).
