Word cloud is an audience favorite among Poll Everywhere activities. Seeing words pop, fade, and fly across the screen draws so many "oohs" and "aahs" from the audience it’s like having a little fireworks display right on stage.
Two new upgrades help deliver that the poll faster than before. You can now combine words in a word cloud, and present words using a custom gradient color palette. These changes create more colorful, customizable word clouds that are sure to impress the audience.

1. Combine multiple words in a single word cloud response

You can now add an underscore ("_") or tilde ("~") to combine two or more words in a word cloud response. That means submitting "Peanut_Butter" will appear as "Peanut Butter" (without the underscore) in the word cloud. "Peanut" and "Butter" will not be separated into different words, but instead appear as a single, combined phrase.

2. Set a custom gradient color palette for word cloud responses

Poll Everywhere can display word cloud responses in a set of 20 colors. Poll Everywhere would randomly select one of those 20 colors for each word in the word cloud. And you couldn’t customize them. If you had a background that was similar to one of those 20 colors, some words were tough to read.
To improve readability - and creative potential - of word clouds, Poll Everywhere has two new colorful options for presenters to use.

Set custom gradient: You can now set two colors for your word cloud responses. The most popular responses appear with the first color, the least popular appear with the second, and everything else appears with a color in the spectrum between those two. This option is located under message item in the visual settings menu.

Automatic contrasting: If you change the background of your word cloud, but not the color of the responses, Poll Everywhere will automatically adjust the response color to help them stand out against your new background.
