Holga for Canon DSLR... Taking expensive gear and making art that looks technically "bad"? I'm so in.
The only reason I'd go for the Holga camera instead is to be able to not walk around with a big investment around my neck... but I still do that anyway.
As my sister said (upon seeing my pinhole lens):
"so you've effectively got a $2000 equivalent of a black shoebox with a hole in the end?"
"yes, yes i have (an 18megapixel 8fps shoebox)"
