Visuals: There is a minimalist, rounded brown mammoth on top of the company name in a stacked format, white colour, and capitalization. The logo is seen on a surface that is turning to the bottom right to face the screen. Behind the logo is a black blueprint consisting of several lines sketching the outline of the same mammoth albeit comprised of geometric shapes. When the background finishes moving, it also darkens.
