I put together a selection of 200 EmojiOne emoticons for personal use with Spark Messenger, and have secured permission from EmojiOne Inc. to share the emoticon pack with other Spark users.
The emoticons come in two packs with different display sizes, 16x16 and 32x32. The two packs are side-by-side installable, you can use them both at the same time if you would like. The packs are quasi-compatible with other emoticon packs, the usual etc. will always display OK but for best results to use the foods, objects etc. the users on both ends should be using one of the PHX packs (PHX-16 and PHX-32 are fully compatible with each other).
Download the ZIP file(s) for each pack here: https://goo.gl/Hjjjqv
To install & use, place the ZIP file(s) in "\Program Files (x86)\Spark\xtra\emoticons", then open Spark and select your emotion pack under File>Preferences>Appearance.
The fine print:
-Emoji icons provided free by EmojiOne.
-All emoji images belong to EmojiOne Inc., and cannot be extracted for use in other projects.
-To gain access to these emoji images, go here: https://www.emojione.com/developers/download
Special thanks to Marcie @ EmojiOne for her help.
Thanks for sharing Andrew I have in mind to maybe create a pack with some EmojiOne icons to add to Spark. But i'm not sure about it yet (it will involve putting a disclaimer on our Downloads page).
