d30 Emulator - Fudge Die Variant

As I recently reported, I am the proud owner of a set of Fudge dice now, and it occurred to me that those dice would be perfect for d30 emulation. Using the Fudge die as the "tens" column in a d30% roll, the "-" result would indicate a "0" in the tens column, the blank result would indicate "10," and the "+" result would indicate "20," i.e.:

Fudge Die roll	Result	Modified d30% "tens" result
-	0	0
[blank]	1	10
+	2	20

Yes, I know, I'm just swapping one esoteric die for another here, not very practical or widely applicable. But what fun! Doesn't this make you want to acquire a d30 now? Or some Fudge Dice? Look at all the obscure fun you can have generating tables that practically no one will use!
