Why is it that the elephants in Courier Chess sometimes look like elephants and sometimes look like mini-bishops?
The alfil/elephant has 2 designs: an actual elephant, and the mini-bishop (a bishop with its base removed). The actual elephant is made for Chaturanga (probably not for Courier), maybe the code is a bit messed up for that piece.
I have a variant I would like to suggest that I have been calling Powder Keg. It is played on an 8x8 board. In this variant there is the standard piece layout only blacks king begins on D8, and queen on E8. Some of the pieces have additional movements. Kings get to move one square in any direction as well as two squares along diagonals, bishops get full diagonal movement as well as knight movement. Pawns get their normal movements one square forward, diagonal capture, and two squares forward allowed form the starting position, only once per game an extra two square movement, forward or reverse, or a single square movement diagonal forward, diagonal reverse or straight reverse from any position is allowed. You only get the extra cheat pawn move once, but it is meant to be a really powerful pawn structure fix you can make in exchange for a tempo. Coupled with the bishop color change potential it makes for a wild variant that can be played with a standard board.
