JellyTelly (partially found fan-made bumpers for Christian website; 2008-2010s)
JellyTelly is an online Christian-streaming service launched in 2008 by Phil Vischer (creator of VeggieTales). The website includes original shows to watch such as What's in the Bible?, as well as existing Christian shows such as VeggieTales and Hermie and Friends.
Before releasing JellyTelly to the world, Phil Vischer announced that he was looking for animators and motion graphics artists to send in their ideas for logos and bumpers. Fans would e-mail him, and he would send them the JellyTelly logo. The fans would then make the logo, and then it would have to be approved by Phil Vischer to appear on the official JellyTelly website.
Many people created many logos with very creative ideas, such as animating the logo in charcoal. While it is currently unknown how many people made, how many were sent in, and when this "logo bake-off" stopped, (most likely around 2012, when JellyTelly changed their logo) but 30 of them can be found on many different websites, such as YouTube and Vimeo.
