M3D (found direct-to-video series; 1990s)
M3D was a series of 3D animated videos featuring songs and/or nursery rhymes. The series was created by songwriter and composer, Motti Marcel Nottea, and was made somewhere in Israel. Some segments would eventually make their way into Motti Marcel Nottea's other series, Tommy and the Computoys.
The series has 13 volumes. Volumes 1 through 4 have made their way onto the internet as well as 13, but it is unknown if the rest were ever made. Until evidence of additional volumes surfaces, this series can be considered partially found.
M3D shorts were featured on Piggaso's Place, a live-action/animation-blended children's show.
