Inflated Didoms

A didom is a polyform made by joining two doms, diagonal half-dominoes, at their short legs, long legs, hypotenuses, or half long legs. Here are the 13 didoms:

In 1994 Rodolfo Kurchan introduced inflated pentominoes. These were rectangular arrangements of the 12 pentominoes, in which some pentominoes were scaled up by an integer factor.

Here I show convex arrangements of the 13 didoms, in which some didoms are scaled up by an integer factor or √5 times an integer factor.

See also Convex Shapes from the 13 Didoms.

Symmetric shapes are marked with an asterisk (*).
