It might have been difficult to combine blinking GIFs with JPEG artefacts – that said, it wasn't all that bad with the mouse on the ‘next’ link and tapping of the left mouse button to read the next slide, at least it works in Opera :)
True, but the font detracts from the technical content. Presentation of information is important. There are cognitive and psychologic implications that your reader will incur when reading a document written in Comic Sans. There is nothing to be gained from using Comic Sans and it's not difficult to simply not use the font.
It's Comic Sans with JPEG artifacts. The only consolation is that it doesn't blink.
