=== Description ===
diorama may have been the true highlight of the month, but there’s always room for Vocaloid!
Those last ones (aka this list) are all unique in rather different ways, but also worth checking out for various reasons. (The section is mostly there for 1imb0 though, being both undeniably unique and undeniably good.)
papiyon/Chouchou-P also made an awesome piano medley of a bunch of his songs, though not included above since there’s technically no Vocaloid.
